OK, I can understand the lack of forwarders.

If you provisioned with '--dns-backend=BIND9_DLZ' , you would have
found a 'server services' line in smb.conf and it would have look this:

server services = s3fs, rpc, nbt, wrepl, ldap, cldap, kdc, drepl,
winbindd, ntp_signd, kcc, dnsupdate

Note the lack of 'dns' on the end, you can however write this as:

server services = -dns

Both lines mean the same thing, you are going to use BIND9_DLZ and not
to run the internal dns server. Without one of the two lines, the
internal dns server will be run and as you also seem to be running
Bind9, you will now have two dns servers trying to claim port 53.
