[Samba] NS Records for AD-Integrated Zones

[Isaiah Olson]

Hello,

My domain was provisioned using a Windows 2008R2 server as the first DC,
and I then subsequently joined a Samba 4.4.2 DC running on Ubuntu 14.04.4
and using BIND 9.9.5 as the DNS backend. Everything seems to be working
properly after I added an NC replica for the zones as per the
troubleshooting page. All zones resolve and replicate properly, but I
noticed that there are no NS records corresponding to the Samba DC added to
the AD-Integrated DNS zones. I have manually added records for the DC to
all existing zones, but I also noticed that when creating a new AD
integrated zone using the Windows DNS manager, there are only NS records
for the domain controller that I am connected to in the zone by default.

Is this behavior expected? And is there any way to make sure that NS
records are added for all DCs? I could be remembering incorrectly, but I
recall that when our network was using an all Windows AD environment, the
AD zones had NS records for all DCs included by default.

Thanks,
Isaiah
