A customer reported that after correctly configuring Keycloak for authentication, they encountered the error: “Authentication failed, authentication requires session support.”

Although the solution is available in the Red Hat Customer Portal, this requirement does not appear to be documented in the RHDH authentication setup steps. The documentation should explicitly mention that session support must be enabled in the Keycloak configuration to avoid this error.

Requested Fix:

• Update the authentication documentation to include the required session support configuration.
• Add troubleshooting guidance for this specific error message.
• Ensure alignment with current Keycloak/RHSSO requirements.
