[keycloak-user] avoiding save external-Provider-Users localy

Hi all, We are currently using a Keycloak (3.3.0.Final), there you are binding a external sso Provider as "Identity Providers" Until now everything is working fine. Now we figure out that Keycloak are saving the user in its local database ( see http://www.keycloak.org/docs/3.0/server_admin/topics/identity-broker/firs... )<http://www.keycloak.org/docs/3.0/server_admin/topics/identity-broker/first-login-flow.html> According to Keyclaok documentation: Keycloak needs the local users, but we don't know why? It is possibile to avoid saving the user in Keycloak? Thanks and regards Adam
