Known Limitation: Logout with Keycloak SSO

Greenlight v3 does not fully log you out of Keycloak when you log out of Greenlight.

When you sign out of Greenlight, your Keycloak session stays active in the background. If you log in again, you won't be asked for your credentials, you'll be signed in automatically.

The reverse is also true: signing out of Keycloak directly does not log you out of Greenlight.

This happens because Greenlight does not currently support full single logout (SLO) with Keycloak. This is a known, unresolved issue as of April 2025.
