    we want automatize the secondary DNS setup (at this time we add the zone on the secondary DNS, that is outside ispconfig, manually).
    We have read that guide:
    Here is pretty clear that the primary DNS must be the server on which the ispconfig interface is installed. And the secondary DNS is a "mirror" of that main server (basically the main and the mirrored server share the same dns zone and both are authoritative for that particular domain).

    My question is: we have a cluster of (for example) 5 slave ispconfig with 1 master ispconfig. Any of these 5 slave ispconfig server run a primary DNS server.
    Can we add an a slave server on that cluster that mirrorize any of these 5 slave server, in order to use him as secondary DNS server for all of them?
    If this is not possible can we add a slave ispconfig server, and configure him as a mirror of another slave ispconfig server? Or the target of the mirror of the server must be the main ispconfig server on which ispconfig master is installed?

    Thank you

    A slave is always the mirror of one other server, it can not be the mirror of 5 servers at the same time, so you have to choose which of the 5 others is the primary dns for this slave. The primary dns can be a slave, it does not has to be the server that runs the interface. see multiservers etup guide where the secondary dns is a slave of the primary dns which is a slave of the master.
