Postfix refuses POP clients after mysqlizing back end

Hello,

I have attempted to mysqlize the backend of my postfix config. Since doing that I have not been able to connect to my server via pop clients. I am using courier as my pop server. I am suffering authentication failures even though the correct username and password are supplied.

Here is my main.cf file

#debian.de Pastezone

And these are the supporting files that are supposed to convert my postfix configuration to a mysql backend.

#debian.de Pastezone
#debian.de Pastezone
#debian.de Pastezone
#debian.de Pastezone
#debian.de Pastezone
#debian.de Pastezone

And here are my (sanitized) log files:

#debian.de Pastezone

This is really driving me crazy, any help at all would be greatly appreciated.
