[keycloak-user] Question re Keycloak conflicting password policies

Does anyone know the answer to this? A keycloak admin may want to enforce a specific password policy for one APP but a different (and conflicting) password policy for another APP. E.g. first policy requires one special character whereas second policy prohibits any special character. Is this supportable in Keycloak? I am thinking that two realms could be defined to do this but wouldn't that defeat single-sign-on across the realms? Any thoughts? -Richard
