I'm looking forward to use ngIRCd on my Debian box. I need simple as possible ircd with one feature: allow users to protect his nick names from overtaking. It can be done with NICKSERV bots. Unfortunately Debian has no nickserv services packaged yet and this is not an option.

I see ngIRCd has PAM module authentication support which can help me a lot. I can configure ngIRCd to use PAM but I do not know how to allow non registered users to join using PAM.

Can you suggest PAM configuration file, which is going to allow ALL users to connect, but ask for password for registered users on system (or pwd file). This will allow me to protect registred names and allow guests to connect to the server.

That would be nice if this will appears in ngIRCd documentation as well.
