So far any group in the user's token could be used as primary group. Windows doesn't check if the primary group is enabled or not, it just has no meaning. From a POSIXy point of view it can lead to weird results though. * uinfo.cc (check_token_membership): New static function. (internal_getlogin): Only allow enabled groups as primary group.
