CNTRLPLANE-3473: Add external claims sourcing test cases - #31817
CNTRLPLANE-3473: source an arbitrarily large number of groups (default 1200, crosses the ~200 token claim ceiling and Entra ID's 999-per-response Graph API limit; override via EXTERNAL_CLAIMS_GROUP_COUNT)
CNTRLPLANE-3476: performance ladder over increasing group counts (default 200,500,1000,2000; override via EXTERNAL_CLAIMS_GROUP_COUNTS) with SelfSubjectReview round-trip timings logged per count
CNTRLPLANE-3477: complex chained CEL expressions at every pipeline stage (predicate, pathExpression, mappings, groups claim mapping, user validation)
CNTRLPLANE-3479: Graph-like sourcing via the OAuth2 client credentials grant (authentication.type=ClientCredential) with a per-subject path and an array-of-objects response, simulating Entra ID Graph API in CI
Summary by CodeRabbit
Tests
Expanded coverage for OpenID Connect group sourcing with large group sets and configurable group counts.
Added checks for chained expression-based group mappings, user validation, and group sourcing from a Graph-like endpoint using client-credentials authentication.
Added coverage for service-account setup, role assignment, and batched group creation, including request-failure handling.
Added timing measurements for group-sourcing round trips.
Warning: The referenced jira issue has an invalid target version for the target branch this PR targets: expected the story to target the "5.1.0" version, but no target version was set.

Adds Keycloak helpers for bulk group creation and service-account setup. Adds ExternalOIDC tests for large group sets, chained CEL expressions, and groups from a Graph-like endpoint.
Changes
External OIDC group coverage
Layer / File(s)
Summary
Bulk group creation and large-set tests test/extended/authentication/keycloak_client.go, test/extended/authentication/oidc.go
Creates groups in chunks of 100 with up to 10 concurrent requests. Adds configurable tests that verify large group sets and log SelfSubjectReview round-trip times.
Chained CEL mapping coverage test/extended/authentication/oidc.go
Adds a test for chained CEL expressions, claims-based paths and predicates, group mapping, and user validation.
Graph-like source and service-account setup test/extended/authentication/keycloak_client.go, test/extended/authentication/oidc.go
Adds helpers to create or retrieve a confidential service-account client, resolve its user ID, and grant realm-management roles. Adds a test that verifies groups returned by a per-subject Graph-like source.
This PR only adds external OIDC claims-sourcing tests and Keycloak helpers. The timings logged for the group-count ladder and the chained-CEL test include Keycloak login time, so they overstate the SelfSubjectReview latency. Test correctness and production behavior are unaffected, so this is safe to merge. Timing the SelfSubjectReview call alone would make the performance data trustworthy.

Explanation
The title names CNTRLPLANE-3473 and states that the PR adds external claims sourcing test cases. The raw summary confirms that test/extended/authentication/oidc.go gains tests for externally sourced groups at large counts, chained CEL expressions, and a Graph-like client-credentials endpoint, and that keycloak_client.go gains group-creation and service-account helpers. The title matches the main change, which is new test coverage. It does not mention the Keycloak helper changes, but that is a secondary aspect and the title does not need to cover every detail.

Docstring coverage is 100.00% which is sufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 4 functions across 2 files.
Full details: Stable And Deterministic Test Names
Explanation
All Ginkgo titles introduced by the pull request are static descriptive strings. The added Describe and It titles contain no generated identifiers, timestamps, node or namespace names, IP addresses, UUIDs, legacy metadata tokens, or dynamic formatting. Dynamic test values such as testID, group counts, and user names occur only in test bodies and assertion messages.
Full details: Test Structure And Quality
Explanation
PASS. The four new It blocks each target one external-claims behavior or one performance ladder. Each new Eventually call has an explicit timeout and polling interval. New assertions include diagnostic messages. Keycloak resources are removed with the suite's existing namespace cleanup, and the new openshift-config Secret has deferred deletion. The existing helpers used for rollout and configuration waits also have timeouts. Recommendation: consider marking the new blocking It blocks with ote.Informing() before promotion; the check defines this as a recommendation, not a failure.
Full details: Single Node Openshift (Sno) Test Compatibility
Explanation
The four added Ginkgo tests run in the existing serial OIDC suite (oidc.go:49, 1436-1774). They use Keycloak, Authentication APIs, Secrets, and SelfSubjectReview requests. They do not count or schedule nodes, use affinity or topology constraints, test failover, drain, scaling, rescheduling, or multi-endpoint ingress behavior. CreateGroups uses client-side concurrency only and does not create Kubernetes pods.
Full details: Topology-Aware Scheduling Compatibility
Explanation
PASS: The pull request changes only two test/helper files under test/extended/authentication/. The diff adds Keycloak client helpers and external OIDC test cases. It adds no deployment manifests, operator code, controllers, replicas, affinity, topology spread constraints, node selectors, tolerations, or PDBs. The topology-aware scheduling check is therefore not applicable.
Full details: Ote Binary Stdout Contract
Explanation
No process-level stdout write was introduced. The only added output calls are g.GinkgoWriter.Printf inside It test bodies, which the contract permits. The new top-level registration and helper code contain no fmt.Print*, log, klog, os.Stdout, or suite-level output configuration.
Full details: No-Weak-Crypto
Explanation
The pull request adds Keycloak group/client helpers and external-claims tests only. The changed code contains no MD5, SHA-1, DES/3DES, RC4, Blowfish, or ECB usage, no custom cryptographic implementation, and no comparison of secrets or tokens. The only crypto-related import, crypto/tls, is pre-existing and unchanged.
Full details: Container-Privileges
Explanation
PASS: The PR changes only Go test/client code. It adds no container or Kubernetes manifest fields for privileged mode, hostPID, hostNetwork, hostIPC, SYS_ADMIN, root execution, or allowPrivilegeEscalation. The existing NamespacePodSecurityLevel = api.LevelPrivileged setting is unchanged from the base revision and is not introduced by this PR.
Full details: No-Sensitive-Data-In-Logs
Explanation
The pull request adds two GinkgoWriter.Printf calls. They log only group counts and round-trip durations. No added log statement prints passwords, client secrets, access tokens, email addresses, hostnames, or response data. Credentials are used in Keycloak requests and Kubernetes Secret data, but are not logged.
Full details: Microshift Test Compatibility
Explanation
The PR adds four unguarded Ginkgo tests under the existing [sig-auth][Suite:openshift/auth/external-oidc][Serial][Slow][Disruptive] suite. The tests configure config.openshift.ioAuthentication objects through configv1 and call kubeAPIServerLatestRevision/expectKubeAPIServerRevisionUnchanged, which access operator.openshift.ioKubeAPIServers at oidc.go:1459, 1531, 1594, 1721-1723, and related helper lines 1950-1965. The test names and enclosing suite have no [Skipped:MicroShift] or [apigroup:...] tag, and the file has no exutil.IsMicroShiftCluster() skip guard. These API groups are unavailable on MicroShift.
Resolution
MicroShift compatibility notice: These tests use config.openshift.io and operator.openshift.io APIs that are not available on MicroShift. Add appropriate [apigroup:config.openshift.io] and [apigroup:operator.openshift.io] tags, add [Skipped:MicroShift], or guard the tests with exutil.IsMicroShiftCluster() and g.Skip(). Because the tests are [Serial], verify with /payload-job periodic-ci-openshift-microshift-release-4.22-periodics-e2e-aws-ovn-ocp-conformance-serial if they should run on MicroShift.
Full details: Ipv6 And Disconnected Network Test Compatibility
Explanation
The new serial Graph-like Ginkgo test builds tokenEndpoint with fmt.Sprintf("https://%s/realms/...", hostname) at test/extended/authentication/oidc.go:1718. hostname comes from the admitted route ingress host at keycloakHostname/admittedURLForRoute, so an IPv6 literal would be inserted without brackets. The test uses the cluster-local Keycloak route and does not require public-internet connectivity.
Resolution
IPv6 and disconnected network compatibility notice: This test may contain IPv4 assumptions or external connectivity requirements that will fail in IPv6-only disconnected environments. Please verify your test works on IPv6 by running an additional CI job: /payload-job periodic-ci-openshift-release-master-nightly-4.22-e2e-metal-ipi-serial-ovn-ipv6 Build the token endpoint with IPv6-safe URL construction, such as net.JoinHostPort(hostname, "443"), before adding the path. Use the IPv6-aware host when constructing the URL.

GrantRealmManagementRoles fails on the master realm because realm-management does not exist there.
kc.adminURL points at /admin/realms/master, and the only caller (the Graph-like test in oidc.go) targets that realm. The master realm has no realm-management client. Keycloak provides master-realm in the master realm, and <realm>-realm clients for other realms. See the Keycloak Server Administration Guide, "Master realm access control".
GetClientByClientID("realm-management") therefore returns "not found". GrantRealmManagementRoles returns an error, and the new client-credentials test fails at the GrantRealmManagementRoles step.
Select the management client name from kc.realm:

The deferred delete runs before AfterAll resets Authentication. The source does not establish a concrete failure from that temporary reference. However, _ = discards the delete error and violates the applicable Go requirement. The existing cleanup mechanism reports non-NotFound errors and runs after resetAuthentication.

None.
Reason: All changes are purely additive test code in test/extended/authentication/ — new test cases (CNTRLPLANE-3473, -3476, -3477, -3479) and supporting helpers in keycloak_client.go and oidc.go. No production code is modified. The new tests belong to the [Suite:openshift/auth/external-oidc] suite, which is a dedicated standalone suite defined at pkg/testsuites/standard_suites.go:453 with qualifier name.contains("[Suite:openshift/auth/external-oidc"). It is not part of openshift/conformance/serial or openshift/conformance/parallel. No enrolled second-stage candidate runs the openshift/auth/external-oidc suite: - The serial jobs (serial-1of2/2of2) use TEST_SUITE=openshift/conformance/serial, which filters for name.contains('[Suite:openshift/conformance/serial') — does not match [Suite:openshift/auth/external-oidc]. - The parallel jobs (e2e-gcp-ovn, e2e-aws-ovn-fips) use openshift/conformance/parallel — same exclusion. - All other candidates target domain-specific suites (CSI, builds, image-ecosystem, etc.) unrelated to authentication. The new helpers (CreateGroups, EnsureConfidentialServiceAccountClient, GetServiceAccountUserID, GrantRealmManagementRoles, envPositiveInt, indexedGroupNames, groupsMatchingPrefix) are consumed exclusively by the new tests — no existing test or production code calls them. Coverage gap: the openshift/auth/external-oidc suite is not exercised by any enrolled second-stage candidate. The new tests will be exercised when the suite is run in its dedicated context.

## Configuring realms
Edit this section Report an issue
Once you have an administrative account for the Admin Console, you can configure realms. A realm is a space where you manage objects, including users, applications, roles, and groups. A user belongs to and logs into a realm. One Keycloak deployment can define, store, and manage as many realms as there is space for in the database.
### Using the Admin Console
Edit this section Report an issue
You configure realms and perform most administrative tasks in the Keycloak Admin Console.
Prerequisites
* You need an administrator account. See Creating the first administrator.
Procedure
1. Go to the URL for the Admin Console.
For example, for localhost, use this URL: http://localhost:8080/admin/
Login page
Image: Login page
2. Enter the username and password you created on the Welcome Page or through environment variables as per Creating the initial admin user guide. This action displays the Admin Console.
Admin Console
Image: Admin Console
3. Note the menus and other options that you can use:
* Click the menu labeled Master to pick a realm you want to manage or to create a new one.
* Click the top right list to view your account or log out.
* Hover over a question mark ? icon to show a tooltip text that describes that field. The image above shows the tooltip in action.
* Click a question mark ? icon to show a tooltip text that describes that field. The image above shows the tooltip in action.
| Export files from the Admin Console are not suitable for backups or data transfer between servers. Only boot-time exports are suitable for backups or data transfer between servers.
### The master realm
Edit this section Report an issue
In the Admin Console, two types of realms exist:
* `Master realm` - This realm was created for you when you first started Keycloak. It contains the administrator account you created at the first login. Use the master realm only to create and manage the realms in your system.
* `Other realms` - These realms are created by the administrator in the master realm. In these realms, administrators manage the users in your organization and the applications they need. The applications are owned by the users.
Realms and applications
Image: Realms and applications
Realms are isolated from one another and can only manage and authenticate the users that they control. Following this security model helps prevent accidental changes and follows the tradition of permitting user accounts access to only those privileges and powers necessary for the successful completion of their current task.
Additional resources
* See Dedicated Realm Admin Consoles if you want to disable the master realm and define administrator accounts within any new realm you create. Each realm has its own dedicated Admin Console that you can log into with local accounts.
### Creating a realm
Edit this section Report an issue
You create a realm to provide a management space where you can create users and give them permissions to use applications. At first login, you are typically in the master realm, the top-level realm from which you create other realms.
When deciding what realms you need, consider the kind of isolation you want to have for your users and applications. For example, you might create a realm for the employees of your company and a separate realm for your customers. Your employees would log into the employee realm and only be able to visit internal company applications. Customers would log into the customer realm and only be able to interact with customer-facing apps.
Procedure
1. Click Keycloak next to master realm, then click Create Realm.
Add realm menu
Image: Add realm menu
2. Enter a name for the realm.
3. Click Create.
Create realm
Image: Create realm
The current realm is now set to the realm you just created. You can switch between realms by clicking the realm name in the menu.
## Controlling access to the Admin Console
Edit this section Report an issue
Each realm created on the Keycloak has a dedicated Admin Console from which that realm can be managed. The `master` realm is a special realm that allows admins to manage more than one realm on the system. You can also define fine-grained access to users in different realms to manage the server. This chapter goes over all the scenarios for this.
### Master realm access control
Edit this section Report an issue
The `master` realm in Keycloak is a special realm and treated differently than other realms. Users in the Keycloak `master` realm can be granted permission to manage zero or more realms that are deployed on the Keycloak server. When a realm is created, Keycloak automatically creates various roles that grant fine-grain permissions to access that new realm. Access to The Admin Console and Admin REST endpoints can be controlled by mapping these roles to users in the `master` realm. It’s possible to create multiple superusers, as well as users that can only manage specific realms.
#### Global roles
There are two realm-level roles in the `master` realm. These are:
* admin
* create-realm
Users with the `admin` role are superusers and have full access to manage any realm on the server. Users with the `create-realm` role are allowed to create new realms. They will be granted full access to any new realm they create.
#### Realm specific roles
Admin users within the `master` realm can be granted management privileges to one or more other realms in the system. Each realm in Keycloak is represented by a client in the `master` realm. The name of the client is `<realm name>-realm`. These clients each have client-level roles defined which define varying level of access to manage an individual realm.
The roles available are:
* view-realm
* view-users
* view-clients
* view-events
* manage-realm
* manage-users
* create-client
* manage-clients
* manage-events
* view-identity-providers
* manage-identity-providers
* impersonation
Assign the roles you want to your users and they will only be able to use that specific part of the administration console.
| Admins with the `manage-users` role will only be able to assign admin roles to users that they themselves have. So, if an admin has the `manage-users` role but doesn’t have the `manage-realm` role, they will not be able to assign this role.
### Dedicated realm admin consoles
Edit this section Report an issue
Each realm has a dedicated Admin Console that can be accessed by going to the url `/admin/{realm-name}/console`. Users within that realm can be granted realm management permissions by assigning specific user role mappings.
Each realm has a built-in client called `realm-management`. You can view this client by going to the `Clients` left menu item of your realm. This client defines client-level roles that specify permissions that can be granted to manage the realm.
* view-realm
* view-users
* view-clients
* view-events
* manage-realm
* manage-users
* create-client
* manage-clients
* manage-events
* view-identity-providers
* manage-identity-providers
* impersonation
Assign the roles you want to your users and they will only be able to use that specific part of the administration console.

| Fine Grain Admin Permissions is Preview and is not fully supported. This feature is disabled by default. To enable start the server with `--features=preview` or `--features=admin-fine-grained-authz`
Sometimes roles like `manage-realm` or `manage-users` are too coarse grain and you want to create restricted admin accounts that have more fine grain permissions. Keycloak allows you to define and assign restricted access policies for managing a realm. Things like:
* Managing one specific client
* Managing users that belong to a specific group
#### Managing one specific client
Let’s look first at allowing an admin to manage one client and one client only. In our example, we have a realm called `test` and a client called `sales-application`. In the realm `test` we will give a user in that realm permission to only manage that application.
| You cannot do cross realm fine grain permissions. Admins in the `master` realm are limited to the predefined admin roles defined in previous chapters.
##### Permission setup
The first thing we must do is login to the Admin Console so we can set up permissions for that client. We navigate to the management section of the client, we want to define fine-grain permissions for.
Client management
Image: Fine grain client
You should see a tab menu item called `Permissions`. Click on that tab.
Client permissions tab
Image: Fine grain client permissions tab
By default, each client is not enabled to do fine grain permissions. So turn the `Permissions Enabled` switch to on to initialize permissions.
| If you turn the `Permissions Enabled` switch to off, it will delete any and all permissions you have defined for this client.
Client permissions tab

When you switch `Permissions Enabled` to on, it initializes various permission objects behind the scenes using Authorization Services. For this example, we’re interested in the `manage` permission for the client. Clicking on that will redirect you to the permission that handles the `manage` permission for the client. All authorization objects are contained in the `realm-management` client’s `Authorization` tab.
Client manage permission

When first initialized the `manage` permission does not have any policies associated with it. You will need to create one by going to the policy tab. To get there fast, click on the `Authorization` link shown in the above image. Then click on the policies tab.
There’s a pull down menu on this page called `Create policy`. </excerpt>

<excerpt>citeturn1search0 [wordlim: 200] Crawled: yesterday; Users in the Keycloak `master` realm can be granted permission to manage zero or more realms that are deployed on the Keycloak server. ... Admin users within the `master` realm can be granted management privileges to one or more other realms in the system. ... c:\> kcadm create components -r demorealm -s name=rsa-generated -s providerId=rsa-generated -s providerType=org.keycloak.keys.KeyProvider -s parentId=959844c1-d149-41d7-8359-6aa527fca0b0 -s "config.priority=[\"101\"]" -s "config.enabled=[\"true\"]" -s "config.active=[\"true\"]" -s "config.keySize=[\"2048\"]"
#### Setup and configuration of Keycloak server
Install a Kerberos client on your machine.
Procedure
1. Install a Kerberos client. If your machine runs Fedora, Ubuntu, or RHEL, install the freeipa-client package, containing a Kerberos client and other utilities.
2. Configure the Kerberos client (on Linux, the configuration settings are in the /etc/krb5.conf file ).
Add your Kerberos realm to the configuration and configure the HTTP domains your server runs on.
For example, for the MYDOMAIN.ORG realm, you can configure the `domain_realm` section like this:
`[domain_realm]
.mydomain.org = MYDOMAIN.ORG
mydomain.org = MYDOMAIN.ORG`
3. Export the keytab file with the HTTP principal and ensure the file is accessible to the process running the Keycloak server. For production, ensure that the file is readable by this process only.
For the MIT Kerberos example above, we exported keytab to the `/tmp/http.keytab` file. If your Key Distribution Centre (KDC) and Keycloak run on the same host, the file is already available.
## Controlling access to the Admin Console
Edit this section Report an issue
Each realm created on the Keycloak has a dedicated Admin Console from which that realm can be managed. The `master` realm is a special realm that allows admins to manage more than one realm on the system. You can also define fine-grained access to users in different realms to manage the server. This chapter goes over all the scenarios for this.
### Master realm access control
Edit this section Report an issue
The `master` realm in Keycloak is a special realm and treated differently than other realms. Users in the Keycloak `master` realm can be granted permission to manage zero or more realms that are deployed on the Keycloak server. When a realm is created, Keycloak automatically creates various roles that grant fine-grain permissions to access that new realm. Access to The Admin Console and Admin REST endpoints can be controlled by mapping these roles to users in the `master` realm. It’s possible to create multiple superusers, as well as users that can only manage specific realms.
#### Global roles
There are two realm-level roles in the `master` realm. These are:
* admin
* create-realm
Users with the `admin` role are superusers and have full access to manage any realm on the server. Users with the `create-realm` role are allowed to create new realms. They will be granted full access to any new realm they create.
#### Realm specific roles
Admin users within the `master` realm can be granted management privileges to one or more other realms in the system. Each realm in Keycloak is represented by a client in the `master` realm. The name of the client is `<realm name>-realm`. These clients each have client-level roles defined which define varying level of access to manage an individual realm.
The roles available are:
* view-realm
* view-users
* view-clients
* view-events
* manage-realm
* manage-users
* create-client
* manage-clients
* manage-events
* view-identity-providers
* manage-identity-providers
* impersonation
Assign the roles you want to your users and they will only be able to use that specific part of the administration console.
| Admins with the `manage-users` role will only be able to assign admin roles to users that they themselves have. So, if an admin has the `manage-users` role but doesn’t have the `manage-realm` role, they will not be able to assign this role.
### Dedicated realm admin consoles
Edit this section Report an issue
Each realm has a dedicated Admin Console that can be accessed by going to the url `/admin/{realm-name}/console`. Users within that realm can be granted realm management permissions by assigning specific user role mappings.
Each realm has a built-in client called `realm-management`. You can view this client by going to the `Clients` left menu item of your realm. This client defines client-level roles that specify permissions that can be granted to manage the realm.
* view-realm
* view-users
* view-clients
* view-events
* manage-realm
* manage-users
* create-client
* manage-clients
* manage-events
* view-identity-providers
* manage-identity-providers
* impersonation
Assign the roles you want to your users and they will only be able to use that specific part of the administration console.
### Fine grain admin permissions
Edit this section Report an issue
| Fine Grain Admin Permissions is Preview and is not fully supported. This feature is disabled by default. To enable start the server with `--features=preview` or `--features=admin-fine-grained-authz`
Sometimes roles like `manage-realm` or `manage-users` are too coarse grain and you want to create restricted admin accounts that have more fine grain permissions. Keycloak allows you to define and assign restricted access policies for managing a realm. Things like:
* Managing one specific client
* Managing users that belong to a specific group
* Managing membership of a group
* Limited user management.
* Fine grain impersonation control
* Being able to assign a specific restricted set of roles to users.
* Being able to assign a specific restricted set of roles to a composite role.
* Being able to assign a specific restricted set of roles to a client’s scope.
* New general policies for viewing and managing users, groups, roles, and clients.
There are some important things to note about fine grain admin permissions:
* Fine grain admin permissions were implemented on top of Authorization Services. It is highly recommended that you read up on those features before diving into fine grain permissions.
* Fine grain permissions are only available within dedicated admin consoles and admins defined within those realms. You cannot define cross-realm fine grain permissions.
* Fine grain permissions are used to grant additional permissions. You cannot override the default behavior of the built-in admin roles.
If Keycloak finds an entry by using the `KEY_ONLY` resolver, Keycloak returns that entry. If Keycloak uses all resolvers, Keycloak returns an empty secret.
A list of the currently available resolvers follows:
Name | Description
--- | ---
KEY_ONLY | Keycloak ignores the realm name and uses the key from the vault expression.
REALM_UNDERSCORE_KEY | Keycloak combines the realm and key by using an underscore character. Keycloak escapes occurrences of underscores in the realm or key with another underscore character. For example, if the realm is called `master_realm` and the key is `smtp_key`, the combined key is `master__realm_smtp__key`.
REALM_FILESEPARATOR_KEY | Keycloak combines the realm and key by using the platform file separator character.
FACTORY_PROVIDED | Keycloak combines the realm and key by using the vault provider factory’s `VaultKeyResolver`, allowing the creation of a custom key resolver by extending an existing factory and implementing the `getFactoryResolver` method.
If you have not configured a resolver for the built-in providers, Keycloak selects the `REALM_UNDERSCORE_KEY`.
#### Listing existing realms
This command returns a list of all realms.
$ kcadm.sh get realms
| Keycloak filters the list of realms on the server to return realms a user can see only.
The list of all realm attributes can be verbose, and most users are interested in a subset of attributes, such as the realm name and the enabled status of the realm. You can specify the attributes to return by using the `--fields` option.
$ kcadm.sh get realms --fields realm,enabled
You can display the result as comma-separated values.
$ kcadm.sh get realms --fields realm --format csv --noquotes
#### Getting a specific realm
Append a realm name to a collection URI to get an individual realm.
$ kcadm.sh get realms/master
#### Updating a realm
1. Use the `-s` option to set new values for the attributes when you do not want to change all of the realm’s attributes.
For example:
$ kcadm.sh update realms/demorealm -s enabled=false
2. If you want to set all writable attributes to new values:
1. Run a `get` command.
2. Edit the current values in the JSON file.
3. Resubmit.
For example:
$ kcadm.sh get realms/demorealm > demorealm.json
$ vi demorealm.json
$ kcadm.sh update realms/demorealm -f demorealm.json
#### Deleting a realm
Run the following command to delete a realm:
$ kcadm.sh delete realms/demorealm
#### Turning on all login page options for the realm
Set the attributes that control specific capabilities to `true`.
For example:
$ kcadm.sh update realms/demorealm -s registrationAllowed=true -s registrationEmailAsUsername=true -s rememberMe=true -s verifyEmail=true -s resetPasswordAllowed=true -s editUsernameAllowed=true
#### Listing the realm keys
Use the `get` operation on the `keys` endpoint of the target realm.
$ kcadm.sh get keys -r demorealm
#### Generating new realm keys
1. Get the ID of the target realm before adding a new RSA-generated key pair.
For example:
$ kcadm.sh get realms/demorealm --fields id --format csv --noquotes
2. Add a new key provider with a higher priority than the existing providers as revealed by `kcadm.sh get keys -r demorealm`.
For example:
* Linux:
$ kcadm.sh create components -r demorealm -s name=rsa-generated -s providerId=rsa-generated -s providerType=org.keycloak.keys.KeyProvider -s parentId=959844c1-d149-41d7-8359-6aa527fca0b0 -s 'config.priority=["101"]' -s 'config.enabled=["true"]' -s 'config.active=["true"]' -s 'config.keySize=["2048"]'
* Windows:
c:\> kcadm create components -r demorealm -s name=rsa-generated -s providerId=rsa-generated -s providerType=org.keycloak.keys.KeyProvider -s parentId=959844c1-d149-41d7-8359-6aa527fca0b0 -s "config.priority=[\"101\"]" -s "config.enabled=[\"true\"]" -s "config.active=[\"true\"]" -s "config.keySize=[\"2048\"]"
3. Set the `parentId` attribute to the value of the target realm’s ID.
The newly added key is now the active key, as revealed by `kcadm.sh get keys -r demorealm`.
1. To list assigned realm roles for the composite role, specify the target composite role by name (`--rname` option) or ID (`--rid` option).
For example:
$ kcadm.sh get-roles -r demorealm --rname testrole
2. Use the `--effective` option to list effective realm roles.
For example:
$ kcadm.sh get-roles -r demorealm --rname testrole --effective
3. Use the `--available` option to list realm roles that you can add to the composite role.
For example:
$ kcadm.sh get-roles -r demorealm --rname testrole --available
#### Listing assigned, available, and effective client roles for a composite role
Use the `get-roles` command to list assigned, available, and effective client roles for a composite role.
1. To list assigned client roles for the composite role, you can specify the target composite role by name (`--rname` option) or ID (`--rid` option) and client by the clientId attribute (`--cclientid` option) or ID (`--cid` option).
For example:
$ kcadm.sh get-roles -r demorealm --rname testrole --cclientid realm-management
2. Use the `--effective` option to list effective realm roles.
For example:
$ kcadm.sh get-roles -r demorealm --rname testrole --cclientid realm-management --effective
3. Use the `--available` option to list realm roles that you can add to the target composite role.
For example:
$ kcadm.sh get-roles -r demorealm --rname testrole --cclientid realm-management --available

CHAPTER 11. MANAGING ACCESS TO REALM RESOURCES
# CHAPTER 11. MANAGING ACCESS TO REALM RESOURCES
Each realm created on the Red Hat build of Keycloak has a dedicated Admin Console from which that realm can be managed. The **master** realm is a special realm that allows admins to manage more than one realm on the system. This chapter goes over all the scenarios for this.
## 11.1. MASTER REALM ACCESS CONTROL
The **master** realm in Red Hat build of Keycloak is a special realm and treated differently than other realms. Users in the Red Hat build of Keycloak **master** realm can be granted permission to manage zero or more realms that are deployed on the Red Hat build of Keycloak server. When a realm is created, Red Hat build of Keycloak automatically creates various roles that grant permissions to access that new realm. Access to The Admin Console and Admin REST endpoints can be controlled by mapping these roles to users in the **master** realm. It’s possible to create multiple superusers, as well as users that can only manage specific realms.
### 11.1.1. Global roles
There are two realm-level roles in the **master** realm. These are:
- admin
- create-realm
Users with the **admin** role are superusers and have full access to manage any realm on the server. Users with the **create-realm** role are allowed to create new realms. They will be granted full access to any new realm they create.

### 6.1. Configuring a new regular user for use with Client Registration CLI
Procedure
1. Log in to the Admin Console (for example, http://localhost:8080/admin) as `admin`.
2. Select a realm to administer.
3. If you want to use an existing user, select that user to edit; otherwise, create a new user.
4. Select Role Mapping, Assign role. From the option list, click Filter by clients. In the search bar, type `manage-clients`. Select the role, or if you are in the master realm, select the one with NAME-realm, where `NAME` is the name of the target realm. You can grant access to any other realm to users in the master realm.
5. Click Assign to grant a full set of client management permissions. Another option is to choose view-clients for read-only or create-client to create new clients.
6. Select Available Roles, manage-client to grant a full set of client management permissions. Another option is to choose view-clients for read-only or create-client to create new clients.
| These permissions grant the user the capability to perform operations without the use of Initial Access Token or Registration Access Token.
It is possible to not assign any `realm-management` roles to a user. In that case, a user can still log in with the Client Registration CLI but cannot use it without an Initial Access Token. Trying to perform any operations without a token results in a 403 Forbidden error.
The administrator can issue Initial Access Tokens from the Admin Console in the Clients area on the Initial Access Token tab.

<title>Realm and Multi-Tenancy - Alauda Build of Keycloak</title>
<location>https://docs.alauda.cn/keycloak/26.4/en/concepts/10-realm_and_tenant.html</location>
<excerpt>citeturn0search2 [wordlim: 200] Crawled: today; Every Keycloak installation includes a built-in Realm called master. ... Roles | Realm-level and client-level roles are scoped to their Realm
# #Realm and Multi-Tenancy
## #What Is a Realm
A Realm is the foundational isolation unit in Keycloak. Each Realm manages its own set of users, credentials, roles, groups, clients, and authentication policies independently from other Realms. Realms do not share user databases or configuration, making them the primary mechanism for multi-tenancy in Keycloak.
Think of a Realm as a dedicated identity domain — analogous to a tenant in a multi-tenant SaaS application.
## #The master Realm
Every Keycloak installation includes a built-in Realm called master. The `master` Realm is the top-level administrative domain and is used exclusively for:
* Managing other Realms (creating, configuring, and deleting them)
* Managing Keycloak server-level settings
* Hosting the Keycloak Admin Console
Security Recommendation
Do not use the `master` Realm to manage application users or host application clients. Create dedicated Realms for each application or tenant to maintain proper isolation.

## Controlling access to the Admin Console
Edit this section Report an issue
Each realm created on the Keycloak has a dedicated Admin Console from which that realm can be managed. The `master` realm is a special realm that allows admins to manage more than one realm on the system. You can also define fine-grained access to users in different realms to manage the server. This chapter goes over all the scenarios for this.
### Master realm access control
Edit this section Report an issue
The `master` realm in Keycloak is a special realm and treated differently than other realms. Users in the Keycloak `master` realm can be granted permission to manage zero or more realms that are deployed on the Keycloak server. When a realm is created, Keycloak automatically creates various roles that grant fine-grain permissions to access that new realm. Access to The Admin Console and Admin REST endpoints can be controlled by mapping these roles to users in the `master` realm. It’s possible to create multiple superusers, as well as users that can only manage specific realms.
#### Global roles
There are two realm-level roles in the `master` realm. These are:
* admin
* create-realm
Users with the `admin` role are superusers and have full access to manage any realm on the server. Users with the `create-realm` role are allowed to create new realms. They will be granted full access to any new realm they create.
#### Realm specific roles
Admin users within the `master` realm can be granted management privileges to one or more other realms in the system. Each realm in Keycloak is represented by a client in the `master` realm. The name of the client is `<realm name>-realm`. These clients each have client-level roles defined which define varying level of access to manage an individual realm.
The roles available are:
* view-realm
* view-users
* view-clients
* view-events
* manage-realm
* manage-users
* create-client
* manage-clients
* manage-events
* view-identity-providers
* manage-identity-providers
* impersonation
Assign the roles you want to your users and they will only be able to use that specific part of the administration console.
| Admins with the `manage-users` role will only be able to assign admin roles to users that they themselves have. So, if an admin has the `manage-users` role but doesn’t have the `manage-realm` role, they will not be able to assign this role.
### Dedicated realm admin consoles

### Fine grain admin permissions
Edit this section Report an issue
| Fine Grain Admin Permissions is Preview and is not fully supported. This feature is disabled by default. To enable start the server with `--features=preview` or `--features=admin-fine-grained-authz`
Sometimes roles like `manage-realm` or `manage-users` are too coarse grain and you want to create restricted admin accounts that have more fine grain permissions. Keycloak allows you to define and assign restricted access policies for managing a realm. Things like:
* Managing one specific client
* Managing users that belong to a specific group
The Admin CLI makes HTTP requests to Admin REST endpoints. Access to the Admin REST endpoints requires authentication.
| Consult the Admin REST API documentation for details about JSON attributes for specific endpoints.
1. Start an authenticated session by logging in. You can now perform create, read, update, and delete (CRUD) operations.
For example:
* Linux:
$ kcadm.sh config credentials --server http://localhost:8080 --realm demo --user admin --client admin
$ kcadm.sh create realms -s realm=demorealm -s enabled=true -o
$ CID=$(kcadm.sh create clients -r demorealm -s clientId=my_client -s 'redirectUris=["http://localhost:8980/myapp/*"]' -i)
$ kcadm.sh get clients/$CID/installation/providers/keycloak-oidc-keycloak-json
* Windows:
c:\> kcadm config credentials --server http://localhost:8080 --realm demo --user admin --client admin
c:\> kcadm create realms -s realm=demorealm -s enabled=true -o
c:\> kcadm create clients -r demorealm -s clientId=my_client -s "redirectUris=[\"http://localhost:8980/myapp/*\"]" -i > clientid.txt
### Authenticating
When you log in with the Admin CLI, you specify:
* A server endpoint URL
* A realm
* A user name
Another option is to specify a clientId only, which creates a unique service account for you to use.
When you log in using a user name, use a password for the specified user. When you log in using a clientId, you need the client secret only, not the user password. You can also use the `Signed JWT` rather than the client secret.
Ensure the account used for the session has the proper permissions to invoke Admin REST API operations. For example, the `realm-admin` role of the `realm-management` client can administer the realm of the user.
Two primary mechanisms are available for authentication. One mechanism uses `kcadm config credentials` to start an authenticated session.
$ kcadm.sh config credentials --server http://localhost:8080 --realm master --user admin
This mechanism maintains an authenticated session between the `kcadm` command invocations by saving the obtained access token and its associated refresh token. It can maintain other secrets in a private configuration file. See the next chapter for more information.
The second mechanism authenticates each command invocation for the duration of the invocation. This mechanism increases the load on the server and the time spent on round trips obtaining tokens. The benefit of this approach is that it is unnecessary to save tokens between invocations, so nothing is saved to disk. Keycloak uses this mode when the `--no-config` argument is specified.
For example, when performing an operation, specify all the information required for authentication.
$ kcadm.sh get realms --no-config --server http://localhost:8080 --realm master --user admin
Run the `kcadm.sh help` command for more information on using the Admin CLI.
#### Listing existing realms
This command returns a list of all realms.
$ kcadm.sh get realms
| Keycloak filters the list of realms on the server to return realms a user can see only.
The list of all realm attributes can be verbose, and most users are interested in a subset of attributes, such as the realm name and the enabled status of the realm. You can specify the attributes to return by using the `--fields` option.
$ kcadm.sh get realms --fields realm,enabled
You can display the result as comma-separated values.
$ kcadm.sh get realms --fields realm --format csv --noquotes
#### Getting a specific realm
Append a realm name to a collection URI to get an individual realm.
$ kcadm.sh get realms/master
#### Updating a realm
1. Use the `-s` option to set new values for the attributes when you do not want to change all of the realm’s attributes.
For example:
$ kcadm.sh update realms/demorealm -s enabled=false
2. If you want to set all writable attributes to new values:
1. Run a `get` command.
2. Edit the current values in the JSON file.
3. Resubmit.
For example:
$ kcadm.sh get realms/demorealm > demorealm.json
$ vi demorealm.json
$ kcadm.sh update realms/demorealm -f demorealm.json
#### Deleting a realm
Run the following command to delete a realm:
$ kcadm.sh delete realms/demorealm
#### Turning on all login page options for the realm
Set the attributes that control specific capabilities to `true`.
For example:
$ kcadm.sh update realms/demorealm -s registrationAllowed=true -s registrationEmailAsUsername=true -s rememberMe=true -s verifyEmail=true -s resetPasswordAllowed=true -s editUsernameAllowed=true
#### Listing the realm keys
Use the `get` operation on the `keys` endpoint of the target realm.
$ kcadm.sh get keys -r demorealm
#### Generating new realm keys
1. Get the ID of the target realm before adding a new RSA-generated key pair.
For example:
$ kcadm.sh get realms/demorealm --fields id --format csv --noquotes
2. Add a new key provider with a higher priority than the existing providers as revealed by `kcadm.sh get keys -r demorealm`.
For example:
* Linux:

keycloak Admin: Client could not be updated: HTTP 403 Forbidden #51105

Hello Keycloak community, I am using Keycloak 26.7.0 and I noticed that a Keycloak admin user cannot disable the default client realm-management in another realm. Steps to reproduce: Create a new realm (for example test-realm).
Login as a Keycloak administrator from the master realm.
Navigate to:
test-realm → Clients → realm-management
Try to disable the client (Enabled = OFF).
Save the changes. The update fails with: Client could not be updated: HTTP 403 Forbidden When checking the client representation through the Admin REST API, I see: "access": {
"view": true,
"configure": false,
"manage": false
} My expectation was that a Keycloak administrator should be able to manage or disable default clients in other realms. Questions: Is this expected behavior in Keycloak 26.7.0?
Is there a specific permission or role required to manage the realm-management client?
Is there any recommended way to disable or remove this client if it is not needed?
Could this be considered a bug, or is there a security reason behind this restriction? Thank you for your help.

I guess this the client keycloak uses to enable management of this realm from the admin console, so delting it is probably blocked for a reason.</excerpt>

### Description
Keycloak creates a bunch of default clients in `master` or new realms:
* `account`: Represents the backend for the account API
* `account-console`: Provides a frontend for user account management.
* `admin-cli`: Used for managing realms via CLI tools like kcadm.sh.
* `broker`: Serves as the backend for identity brokering.
* `security-admin-console`: Manages the admin UI for a specific realm.
* `realm-management`: Backend API for realm-specific management. Does not exist in `master`.

Now it makes a lot of sense that we would want to manage these clients with Terraform. I want to delete some of these clients, but deleting such a resource seems to be nigh impossible via Terraform... </excerpt>

I wrote a script to run diagnostic checks on my Keycloak instance in my deployment. I was surprised by the fact that the Keycloak version is so guarded by default. I found the /admin/serverinfo endpoint, but it won't tell me the version number. I had to add "manage-realm" role to my service-account to be able to see the version number. Why does "view-realm" not work? Is there not a read-only style role that can see the Keycloak version number?

Thank you for the response. I am unsure of how to add the "view-realm" role to my service account in the master realm. The UI does not list my service-account as a client in the master realm. In my non-master realm, if I try to add realm-management client's view-system role to my service account, I receive a 403 error.

There were some changes to the `serverinfo` in the last versions. The version was first restricted and then only available with `manage-realm` permission. It is not available now with `view-realm`. The only way to revert this is using the `view-system` (you need to create this role) and enable the FGAP in the realm (but probably this will be even deleted in the future).

This is almost always a missing realm-management role, not a token problem. In Keycloak, a master-realm admin's access to other realms is granted per-realm: the master realm holds a client called `<realm>-realm` for each realm (so `test-realm`, `staging-realm`, …), and each carries roles like `view-users`, `query-users`, `manage-users`. Your token is fine — the 403 means the user behind it has the `staging-realm` roles but not the `test-realm` ones. The built-in `admin` role in the master realm is a composite that includes the management roles for all realms (and Keycloak adds new realms to it automatically), so a user with the full `admin` role can administer every realm. A 403 on just one realm means the user doesn't have that full composite — they have a narrower, hand-picked set of `*-realm` client roles that includes `staging-realm` but not `test-realm`. Fix it in the master realm → Users → your admin user → Role mapping:
* assign the `admin` role for full cross-realm access, or
* assign the specific `test-realm` client roles you need (at least `view-users`, plus `query-users`/`manage-users` if you also list or modify users).
Once `test-realm`'s `view-users` is mapped, `GET /admin/realms/test/users` will stop returning 403.

Use master-realm for the master realm.
keycloakClientFor targets /admin/realms/master, but GrantRealmManagementRoles always looks up realm-management. Keycloak uses the <realm name>-realm client for administration from the master realm. This lookup can fail on every retry because the retry does not change the client ID.
Select master-realm when kc.realm == "master" and realm-management otherwise. Remove the realm-management reference from the retry rationale.

None.
Reason: All changes are purely additive test code in test/extended/authentication/ (keycloak_client.go +218, oidc.go +409). Four new test cases (CNTRLPLANE-3473, -3476, -3477, -3479) and supporting helpers are registered in the [sig-auth][Suite:openshift/auth/external-oidc][Serial][Slow] suite. No existing test code is modified — no changed assertions, no altered shared helpers, no modified function signatures. New imports (errors, sync, os, sort, strconv) are stdlib with no init-time side effects. Every new method and utility function is called only from the new tests. No enrolled candidate runs the openshift/auth/external-oidc suite: pattern-specific candidates don't match test/extended/authentication/, and the ^.*$ candidates (e2e-gcp-ovn, e2e-aws-ovn-fips, serial-1of2/2of2, metal-ipv6, microshift) run conformance suites that exclude [Suite:openshift/auth/external-oidc][Slow] tests. Running any candidate would not execute any of the changed code. Coverage gap: no second-stage candidate exercises the openshift/auth/external-oidc suite. First-stage images/unit/lint/verify all passed, confirming compilation and static analysis.
- CNTRLPLANE-3473: source an arbitrarily large number of groups (default
1200, crosses the ~200 token claim ceiling and Entra ID's 999-per-response
Graph API limit; override via EXTERNAL_CLAIMS_GROUP_COUNT)
- CNTRLPLANE-3476: performance ladder over increasing group counts (default
200,500,1000,2000; override via EXTERNAL_CLAIMS_GROUP_COUNTS) with
SelfSubjectReview round-trip timings logged per count
- CNTRLPLANE-3477: complex chained CEL expressions at every pipeline stage
(predicate, pathExpression, mappings, groups claim mapping, user validation)
- CNTRLPLANE-3479: Graph-like sourcing via the OAuth2 client credentials
grant (authentication.type=ClientCredential) with a per-subject path and an
array-of-objects response, simulating Entra ID Graph API in CI

Measure only the SelfSubjectReview request. The current timing also includes the Keycloak password grant.
selfSubjectGroups first calls keycloakCli.Authenticate (a password grant to Keycloak) and then creates the SelfSubjectReview. elapsed covers both calls. The log message says "SelfSubjectReview round-trip", so the CNTRLPLANE-3476 data points include Keycloak login time and token-issuance variance. The complex-CEL test at Line 1637–1647 has the same problem.
Get the token first, then time only the SelfSubjectReviews().Create call.

Chai test selection for 62b8d225620f099ffacd3e41c5ecaaf792fd79c2 → main
None.
Reason: All changes are purely additive test code in test/extended/authentication/ — new Keycloak client helpers (CreateGroups, EnsureConfidentialServiceAccountClient, GetServiceAccountUserID, GrantRealmManagementRoles), four new test cases (CNTRLPLANE-3473/3476/3477/3479), and utility functions (envPositiveInt, envPositiveInts, indexedGroupNames, groupsMatchingPrefix). No existing methods, test cases, or production code are modified; every new function is called exclusively by the new test cases. The tests are tagged [Suite:openshift/auth/external-oidc], a custom suite selected only by jobs explicitly configured for it. No candidate job runs this suite — standard conformance (parallel/serial), MicroShift, CSI, builds, image-registry, kubevirt, upgrade, two-node, and vSphere jobs all use different suite selectors. Selecting an unrelated e2e job would not exercise the changed test paths. Coverage gap: no second-stage candidate exercises the openshift/auth/external-oidc suite. The dedicated external-OIDC jobs that run this suite are not enrolled in the pipeline. Reviewers should verify that periodic or post-merge jobs cover these new test cases.
Checked the linked run: Prow reports success. The e2e-aws-external-oidc-upstream-claim-sourcing job completed successfully; its pre-test, openshift-e2e-test-8h, and post-test phases all succeeded. It finished at 2026-11-02 13:49:42 UTC. Prow run.
