That's easy, it is a bug introduced at 4.6.0 (I think that was the
version). You cannot do anything to stop them on a DC. People were
not setting 'idmap config' correctly, so the error message was added.
The only problem is, you cannot use the 'idmap config' lines on a DC,
so you get the error message every time smb.conf is checked.
