Authority means that the nameserver has local content for that query.
Whenever you load a Zone in BIND or PowerDNS you make it authoritative
for that Zone.

I think you're missing the IP or network range you are querying your
server from in the allow-recursion= statement.

In addition to that PowerDNS does not seem to have the zone you set it
up for (vptt.ch?) available locally or it would have answered anyways.

Are there any loglines that may point to such a problem?

It would be best if you could post your pdns.conf as there is many many
ways to configure PowerDNS as a slave/secondary nameserver and without
it all we can do is very wild guessing. ;)

One wild guess that might just be it is: Did you set slave=yes in your
pdns.conf to enable PowerDNS to go fetch to zone via AXFR?
