Does nobody read the Samba wiki ???

As far as I am aware, AD subdomains do not work correctly with Samba AD.
What you have done with the new DC, is what you should have done in the
first place, created a subdomain of your main dns domain and used this
for the AD dns domain and realm.

I think you have two options here and I don't think you are going to
like either ;-)

Shut down your main DNS server and then use the Samba dns servers for
everything in the domain, or start again with your new DC and DNS
subdomain.
