This should be possible using the ldap authentication / authorization 
stuff. I'm not really fluent in it, but I think I saw something like 
this revently. Not related to Nagios, but it solved the same problem. If 
I understood the ldap query correctly :-)

This would require changes to the cgi authorization code, and new 
configuration directives, I guess.

I do it differently, but with the same goal: I have contact information 
set up in a generic way - i.e. 24x7, all states, some contact identifier.

The Nagios users have all their settings in theit ldap directory 
entries, i.e. when, about what, and how they are notified. The 
notification program gets that info from ldap, sees if it has to send a 
notification, and does so according to what the user configured.

In my setup, having group authetication is not necessary because the 
users need to have the notifications set up individually, and thus the 
web browser has the means to determine who is allowed to acces the 
nagios pages on a per-user basis.

Well, much of what you want can alredy be done by setting up the right 
notification commands.
