There seems to be some issue with updating records that I didn't quite 
identify yet. It only seems to bite us on updating records that already 
exist, and basically happen in the middle of the process. So the old 
record gets deleted ok, but no new record is added.
I suspect that's also what is causing your problem here.

An important thing to remember is that the internal DNS server and the 
'dnsserver' RPC that both samba-tool and the DNS MMC talk to are two 
completely separate identities, they're just backed by the same records 
in the AD.

The Bind9 DLZ module and the internal server use the same data to do 
their job. If one works and the other doesn't then your AD data is fine 
and there's a bug in the DNS implementation.
