[Samba] using samba with bind dlz

[Jeff Sadowski]

Bind-9.11 is installed. How do you configure it? Does it need anything
special in the config for samba to build the ...samba.../named.conf file
that I should be able to include in my /etc/named.conf afterwards?

 My guess is that some directory is missing. But if I start fresh and
configure samba with the internal dns it gets all the way through it's
configuration with no errors.

I've tried without named running and with it running and get the same
error. Mayke something missing in the python scripts building the dns file.
