Please don't do that. 

Samba is only supported when using our internal DNS server or
BIND9_DLZ, it is not supported when attempting to host our records
externally.

In particular, when Samba joins as a new DC it strictly requires that
it can find the DNS records created over DCE/RPC and LDAP and expects
those to be in the DNS server at the end of the join.

Please just delegate the Samba domain back to the Samba DC, or point
clients at the Samba DC first, forwarding on to dnsmasq.
