Describe the bug

Starting with Keycloak 26.3.0, a realm-level administrator (user with the realm-admin role in a non-master realm) can no longer use the realm-specific Admin Console.

After authenticating directly against the realm-level console URL (e.g. /admin/<realm>/console/#/), the UI becomes largely unusable: most components do not render correctly and the web console is effectively non-functional.

This workflow worked as expected in 26.2.5 and earlier versions: realm-level administrators were able to access the realm-specific admin console to perform maintenance tasks.

From 26.3.0 through 26.4.7 (latest at time of reporting), realm-level administration appears to be possible only by signing into the master realm Admin Console with a server administrator account and switching to the target realm, which is a functional regression for delegated realm administration.

Version

26.4.7

Regression

• The issue is a regression

Expected behavior

A user with realm-level administrative permissions (e.g., realm-admin in realm Test) should be able to:

1. Navigate to the realm-specific Admin Console endpoint: http://localhost:8080/admin/Test/console/#/
2. Authenticate successfully
3. Use a fully rendered, functional Admin Console UI for that realm (as in 26.2.5 and earlier)

Actual behavior

After logging in to the realm-level Admin Console (/admin/<realm>/console/#/) as the realm admin user:

• The Admin Console UI is broken / mostly not rendered
• Navigation and UI components are not usable
• The console cannot be used to perform administrative tasks from the realm-level entry point

How to Reproduce?

1. Install Keycloak 26.3.0+
2. Create a realm named Test
3. Create a new user in realm Test and grant them the realm-admin role
4. Open the realm-level Admin Console URL, for example: http://localhost:8080/admin/Test/console/#/
5. Log in as the realm-level administrator created in step 3

Observe: the Admin Console UI does not render correctly and is not usable.

Anything else?
