I'm running samba4 on ubuntu (4.0.0+dfsg1-1), on a machine that has had a variety of DHCP-assigned IPs.

When I installed samba4, this machine had the IP of

Now, it has a DHCP assigned value of

dig +short @ machine.corp.example.com:

dig +short @ machine

I'm sure this is samba4 replying, and the upstream forwarding nameserver actually returns the correct ( value for both. samba4 has clearly cached this somewhere.

The logs show nothing of interest, except for:

> Not authoritative for 'machine', forwarding    [so the correct value is coming from the upstream DNS]
