Re: [keycloak-user] Cross Realm authorization

Hi Dmitry, I implemented it based on beercloak. Here in AbstractAdminRessource.java: AuthenticationManager.AuthResult authResult = authManager.authenticateBearerToken(session, realm); if (authResult == null) { throw new NotAuthorizedException("Bearer"); } Still results in Unauthorized. I tried it with an user in master realm, that has "view-users" for the user realm and an admin user from the master realm. Both resulted in an 401 at the mentioned code point. The realm is set to master realm and the session seems to be injected ... Any ideas?

The whole purpose of this is to allow master realm users to administer objects in non-master realms. (Some musings: I dream of having AdminRealmResourceProvider with all that stuff OOTB; the idea has been around for years, but I'm afraid we won't have it in Keycloak anytime soon. Luckily, this can be done at a low price of introducing some boilerplate code into your project.) Good luck, Dmitry Telegin CTO, Acutus s.r.o.
