I would like to have the ability to import a zone or even a configuration with the manual way. It could ba annoying to have a zone ready from an older installation and you have to import it again via the web gui.
The other request is that at the slave configuration the webgui allows you to enter only one master server, although BIND allows more than one in the bind.conf file.
zone2ldap would be the solution.
I have a network with more than one masters for the zone. There are 2 master servers and an anycast IP to select the nearest slave of them, which still is a master for me. Since multiple masters is allowed on bind I thought that I could use it in ZS, just like you can add multiple forwarders.
