[keycloak-user] Web authentication using CAS server

Hello all, We currently have a Jasig CAS server (3.5.x) for Web SSO, with LDAP as authentication backend. I would like to use Keycloak for some new applications, but without users having to log in twice. Is it possible to delegate the authentication in Keycloak to the CAS server ? Has someone managed to integrate Keycloak with an existing CAS setup ? Another option would be to have Keycloak implement the CAS 2.0 protocol, maybe this is something planned ? Thanks, Christophe
