Why aren't you using PBW? No other server is necessary.

Anyway, to answer your question, load a multiplayer game and when you get to the list of empires to log in, scroll all the way down to the bottom and select Game Master (Host). Enter the password and click login. Logged in as host, you can reset any empire's password to a randomly generated number (will not take effect until turn is processed) or process the turn.
