* set domain->last_status = NT_STATUS_SERVER_DISABLED on an ads_connect() failure
* Fix code to use winbind_rpc methods for trusted mixed mode or NT4 domains

  ( this is needed if the DC is upgraded and samba is not reconfigured

* fix bug that caused us to enumerate domain local groups in domains
  other than our own
