[Samba] Wrong local DNS responses from samba4

[Nick Semenkovich]

I'm running samba4 (compiled via git a few days ago, off 5530cc481653) on
Ubuntu, as an AD DC.

Everything works perfectly with the domain, /except/ that Samba seems to be
returning incorrect DNS entries for the local domain computers -- any
thoughts on how to debug this (or where Samba is getting its IPs from?).


As an example:

router/dhcp/upstream DNS is at 192.168.0.1
samba4 is at 192.168.0.2

aio1.corp.example.com is at 192.168.0.171 (and has been for 48+ hours)

[ask upstream router/DHCP for the IP]
$ dig +short @192.168.0.1 aio1.corp.example.com
192.168.0.171
^^ correct ^^

[ask samba4 for the IP]
$ dig +short @192.168.0.2 aio1.corp.example.com
192.168.0.168
^^ wrong ^^


The samba4 server's resolv.conf is:
nameserver 192.168.0.2
nameserver 192.168.0.1
search corp.example.com

smb.conf contains:
dns forwarder = 192.168.0.1


Any thoughts on how to debug this?


Best,
Nick
