Zentyal as DNS Slave server

[rindi]

Hi,

I'm trying to setup a Zentyal Server to be a slave to another DNS Server. The problem is that the Zentyal Web Interface doesn't have that option. If I edit the configuration file in /etc/bind/ with the domain it should be a slave of, and then restart the DNS server through the Web Interface, my entries in that file are lost. What do I need to do so that doesn't happen?

Thanks.
