This looks about right.

It's best to test for dns responses with the tool 'dig', this gives
much valuable output when debugging.

Check if your allow-from (recursor) and allow-recursion (auth server)
settings are allowing for the queries to be answered.

For debugging you can temporarily configure the recursor with
trace=yes - it will then give heaps of output on what it's doing
including of course when it gets a recursive query from a client (such
as the pdns_server in your setup). Be sure to disable this for
production or it will definitely clog up your log files.

About all the recursor settings please see
http://doc.powerdns.com/built-in-recursor.html#recursor-settings and
about the authoritative Server settings are listed at
http://doc.powerdns.com/all-settings.html .

Please also check if you absolutely _must_ run the server in front of
the recursor as it usually is best to separate those functions. ->
