Description Pierre Prinetti 2022-03-03 15:18:04 UTC

+++ This bug was initially created as a clone of Bug #2059515 +++

Description of the problem:

e2e-operator pre-submit e2e jobs are failing on all releases (down to at least 4.8) due to a failure of the test `TestKeycloakAsOIDCPasswordGrantCheckAndGroupSync` (called `TestKeycloakAsOIDCPasswordGrantCheck` 4.9 and older releases).

It was raised in keycloak/keycloak-quickstarts#300 but no update yet, FYI.

> It was raised in keycloak/keycloak-quickstarts#300 but no update yet, FYI.

After a conversation with Alex Szczuczko and Dominik Guhr from the RH SSO (Keycloak) team, I suspect that the mismatch between API and docs will be solved by fixing the docs.

The patch that I propose (attached to this BZ) entails pinning our code to the "legacy" variant of Keycloak's 17.0.0 image, which exhibits the old behaviour. This patch is designed to be backported down to at least 4.8 to unblock the corresponding presubmit tests in the cluster-authentication-operator repository.

I believe that a valid follow-up will be to change the code to use the non-legacy variant: that is, issuing a "start" or "start-dev" command in the container startup.

The action plan:

1. Fix 4.11 by adapting the test logic to Keycloak v17 (see https://github.com/openshift/cluster-authentication-operator/pull/554)
2. Fix previous cluster-authentication-operator releases by pinning Keycloak to the "legacy" (WildFly) variant of v17

Self-marking as VERIFIED as the change only involves test code and tests now pass.
