I wouldn't suggest using this in production, MIT on an AD DC is still

First, there is no point in asking Fedora about this, the dhcp script is 
supplied by Samba (or to be more precise, by myself).

Secondly, it looks like your clients are trying to update their own 
records in AD, which they cannot, because they do not belong to them, so 
stop your clients trying to do this..

Thirdly, this is the wrong place to ask, you should have asked on the 
samba mailing list.
