You can't bind just the internal DNS to localhost and not Samba itself.
And it makes no sense to run a DC, that listens just on localhost. :-)

If you would use BIND9_DLZ, then you could configure BIND to just listen
on localhost, while Samba does on all interaces. But in that case, you
can use BIND at all. ;-)

I would run the caching DNS on a different host and forward requests for
AD zones to your Samba DC. That's the easiest.

Or you do something freaky (it's not a recommendation!): ;-)
- Configure your caching DNS to listen on a different port than :53
- Configure an iptables rule, that forwards all incomming traffic, that
comes through your NIC for port :53 to the other port your caching DNS
is running on.
