Thanks James; but for whatever reason, in my environment the updates don't
succeed at all with the internal DNS. I agree it isn't a BIND issue, but
I've had these TSIG errors for the last few hours (i.e. since adding the
nsupdate utility) and they haven't gone away.

Now, on two DCs, I have manually added the missing DNS entries
(samba_dnsupdate helpfully tells me exactly what I need to add) and I
haven't had a reoccurrence of the TSIG error since.. presumably because the
samba_dnsupdate tool is no longer trying to add any DNS entries. I shall
therefore now also add the DNS entries that the third DC is missing, and
hopefully all shall be well.

There does seem to be an issue using nsupdate with the internal DNS,
though. Is it just me and Mathias that has issues? I think I have worked
around the issue here, rather than actually fixing it - but surely the
internal DNS should work fine with this?

I'm happy to raise a bug report if that would help - but I wanted to check
that I wasn't missing something from my setup, first. This is one of those
things that I assumed must just work fine and therefore I must have
something configured wrong at my end :)

Cheers,

J
