The attached patch fixed up a problem I noticed while testing the
backup/restore tool against a Windows VM DC. Windows has an extra
'CN=DNS Settings' child object underneath the Server object that Samba
doesn't have. This was causing the removal of the server object in the
demote/remove_dc code to fail.
This should hopefully fix the problem reported on the samba mailing list:
CI tests link (in progress).
