Newbie question: What is a secret?

, how to configure this server? I have seen that I must use the users file, but I don't know how to add a new user for this job. And must I change any things on the *.conf Files? Thanks a lot and greets Stefan = Gesendet von Stefan Hilfiker ([EMAIL PROTECTED]) http://get.to/Stefhilfiker
