3.1.5 - Dnssec signing zone - multiserver

When installing ispconfig with multiserver where ispconfig is on one server and bind9 as master on the other server.

When a zone is created, the zone is signed.

After a few days the signature expires and the zone will cease to be trustworthy and then inactive.

The .signed file is unchanged.

When Tools> Resync DNS, the zone is properly signed and starts working. At this point, it is visible that the .signed file has changed.
