Ok, I think I am getting closer. I have defined a new passwd module >>like so:
passwd nas_group { filename = ${raddbdir}/nas_group format = "*NAS-IP-Address:,User-Name" }
Thet creates a username by NAS IP address, I think... you don't want to do that.
See the "man" page for rlm_passwd. It says to create a group attribute for a reason.

OK, yes, I realize that was creating a user name. So if I change that format line to have a Group attribute instead of User-Name, then I have a Group being created by NAS-IP-Address. I still don't get how I can test to make sure that the user is part of this group. I have tried adding the group name to the usergroup table, but whether or not this value is correct (corresponds to the value in the nas_group file) or is even present doesn't make a difference. The user is always getting authenticated. Where does the logic need to lie to check that the user is a part of the named group? Simon
