[Samba] Reverse DNS

Hi Rowland,

I've gone through it a few times. The situation is different in our case
- The server with DHCP is not the AD DC
- The server doesn't have Samba
- The server is not in the same AD DC domain
- The server is a standalone Ubuntu box with other functionalities

The question I have is why is it failing to update the reverse zone when it updates the forward zone, despite the errors in the syslog?

Regards,
Praveen Ghimire
