Are you sure about that ?

 From man smb.conf:

        interfaces (G)

            This option allows you to override the default network 
            list that Samba will use for browsing, name registration and 
            NetBIOS over TCP/IP (NBT) traffic. By default Samba will 
query the
            kernel for the list of all active interfaces and use any 
            except that are broadcast capable.

What I do not really understand is, why go to all the trouble of running 
Bind on the DC and not use it for Samba 4 DNS.
