As you have already noticed yourself, this won't work.

I'm looking for somethink like "server_condition" for the "plain"
authentication method. This would solve my problems, I guess, because I
can't see a substantial difference between the two authentication
methods (when it comes to missing password files that should be handled
graciously.)
