Yes the slave is and feels authoritative for the zone. [1]

Yes it does. [2]

And again: yes. It makes no difference if I append +rec or +norec.

Due to the logfiles the transfer seems to be successful. [4] Btw there
are no errors or warnings in the logfile.

Can you please tell me if the following command leads to sufficent
output? Or can I somehow increase the loglevel?
pdns_server --daemon=no --control-console --query-logging=yes

I appended the output of a query on the slave for each case (existing
record vs non-existing) at the end. [3]

We are using Debian and there it's to most recent version in the repository.
