[NoCat] Docs for NoCatSplash

[Emilio Recio]

Hi,

I just downloaded and installed NoCatSplash (splashd). I have some 
question regarding nocat.conf file. I tried to look in the man pages but 
there were somethings in the nocat.conf that weren't in the man pages.

First off, what I want to do is simple authentication. I have an idea on 
how this is going to work (with some coding on my part php/Perl/etc.), 
and it would be nice if nocat had some provisions for it or docs on how 
it could be accomplished.

1) GatewayMode: it says it's not implemented other than Open. There's no 
mention of Gateway Mode in the man page. What is it for? What are the 
options?

2) Why have LoginTimeout if GatewayMode isn't implemented? If it's 
unrelated, then what exactly is it for?

3) AuthServiceAddr: what is this for and how does AuthService work? It's 
not at all discussed in the man page.

Background:

What I want to do is have a captive portal which asks for one or more 
bit of information (username/password). It sends this login info to a 
backend authentication mechanism (i.e.: PAM, Perl script, shell script, 
RADIUS, etc...) and based on the reply (or return code if it's a script) 
it lets the user through, or keeps the user in the captive portal.

Thanks a lot in advance!
