Quick update:
If I add
domain ncs.k12.de.us
to /etc/resolv.conf on the second DC, names resolve. However, I don't need
this entry on the PDC.
Sincerely,
Dave Hopkins

Subject: [Samba] DNS issue with second samba DC
I have samba4 installed on two systems: ncssamba1 and ncssamba2. ncssamba1 is
the PDC, ncssamba2 was joined to the domain using the instructions here:
http://wiki.samba.org/index.php/Samba4/HOWTO/Join_a_domain_as_a_DC
I had to manually add the DNS information as mentioned on that page. I can add a
user and the user is replicated.
However, I have some issues with DNS resolving hostnames. Specifically, on the
PDC,
$ nslookup ncsfs1
Server: 10.179.2.25
Address: 10.179.2.25#53
Name: ncsfs1.ncs.k12.de.us
Address: 10.179.2.6
But the same system is not found on the second DC
$ nslookup ncsfs1
Server: 10.179.2.24
Address: 10.179.2.24#53
Non-authoritative answer:
*** Can't find ncsfs1: No answer
resolv.conf is identical between the two systems. /usr/local/samba/etc/smb.conf
is likewise the same (except for netbios name)
[global]
workgroup = NEWARKCHARTER
realm = ncs.k12.de.us
netbios name = NCSSAMBA1
server role = active directory domain controller
idmap_ldb:use rfc2307 = yes
dns forwarder=10.1.1.10
allow dns updates=nonsecure and secure
[netlogon]
path = /usr/local/samba/var/locks/sysvol/ncs.k12.de.us/scripts
read only = No
[sysvol]
path = /usr/local/samba/var/locks/sysvol
read only = No
A second DNS issue is that I have other systems that are multihomed (e.g.
10.179.2.13 and 192.168.0.254). Allowing the updates means that the
192.168.0.254 gets added to DNS which I do not want to happen. I want the dns
updates only for the 10.179 addresses. Can this be done?
Finally, I have to relocate the second DC to a new IP address (10.186.2.25/19)
at a remote site. I found instructions here:
https://lists.samba.org/archive/samba-technical/2013-May/092260.html But I
assume I will need to manually create the reverse lookup zone?
Sincerely,
Dave Hopkins
