Ok, I have zero experience with the DLZ stuff, not sure what might be
the problem there.

You can't add or remove zones via dns updates, so this probably needs to
be done via the RPC pipe. This applies for both the internal server and
bind/dlz, maybe Amitay knows more here.

Currently the answer is simple. Apart from "allow dns updates", there is
nothing you can configure with the internal server. As I would assume
that everything you can set via the MMC should apply to both the
internal server and bind/dlz, I think Amitay and me need to figure out
how we handle all those options. In the short term, I will be adding
configuration options in smb.conf. I've got a patch-set that allows for
some primitive forwarding, so that's probably one of the next features
to go in.
