If your main domain is 'example.com' and you use 'ad.example.com' as a
dns subdomain of 'example.com', the Samba DC would be authoritative
for 'ad.example.com', the AD clients would use the DC as their
nameserver for the domain and anything unknown by the DC (google for
instance, or anything in the 'example.com' domain) would be forwarded
to the 'example.com' DNS server.
