I use MySQL as the backend for powerdns. I think is is well configured,
because when I add the NS record of the slave to the domain it is added
to the hidden slave.

    allow-recursion=0.0.0.0/0
    allow-axfr-ips=10.12.3.50
    config-dir=/etc/powerdns
    daemon=yes
    disable-axfr=yes
    disable-tcp=no
    guardian=yes
    launch=gmysql
    lazy-recursion=yes
    local-address=10.12.3.52
    local-port=53
    module-dir=/usr/lib/powerdns
    setgid=pdns
    setuid=pdns
    master=yes
    slave=yes
    slave-cycle-interval=60
    socket-dir=/var/run
    version-string=powerdns
    gmysql-host=127.0.0.1
    gmysql-user=poweradmin
    gmysql-password=secret
    gmysql-dbname=powerdns
    gmysql-supermaster-query=select account from supermasters where
ip='%s'


    mysql> select * from supermasters;
    +------------+------------------+---------+
    | ip         | nameserver       | account |
    +------------+------------------+---------+
    | 10.12.3.50 | master.example.com | admin  |
    +------------+------------------+---------+
    1 row in set (0.00 sec)
