[Samba] Dynamic DNS Update problem -- Ubuntu 12.04

[David Frohlich]

Hello,

I've been struggling with this issue for a few days now. My
configuration is pretty much a stock Ubuntu 12.04 server, with samba4
and bind9 installed from packages.

Samba - 4.0.0alpha18
bind - 9.8.1-P1

I've recompiled the bind package to add dlz support (added flag
--with-dlopen), but I'm getting an error whenever a domain client
connects and attempts to update its DNS record:

Does anyone have an idea of what is wrong?


Thanks
