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.
