group question

Hi, I'm trying to set up a restricted users group to deny access to users so I don't have to create an entry for each one in the users file. Based on the WIKI FAQ, I found: The following entry denies access to a group of users. The same restrictions as above on location in the raddb/users file also apply: DEFAULT Group == "disabled", Auth-Type := Reject Reply-Message = "Your account has been disabled" But where do I specify that group disabled? Is that a group on my linux system or is that group defined within Radius, and if so, where? Thanks Matt mda@unb.ca
