[BZ 1133947] - Unregistered LDAP user without role can login to CLI - introducing loginLocal() method to be able to find out that user is comming from CLI (the case when SubjectManagerRemote.login() is called) and let him fail if it is LDAP user and is not registered in the system. This is now consistent with the REST endpoint, where we assume the registered LDAP user as well.
