Ok, so I put a list of usernames in the users file with an Auth-Type := EAP ?
No. Setting Auth-Type is almost always wrong. In this case, it will do nothing. Instead, put the "good" users into a group (see "man rlm_passwd"). Then, reject everyone who isn't in that group.
Right now, everyone with a valid client certificate is authenticated (nobody is listed in the users file). Once I start enumerating them in the users file, will it have an implicit deny all of everyone who isn't in the users file?
No.
Also - is there a way to define a different users file per NAS?
It's a bit of work, but sure. See "Autz-Type". Alan DeKok. -- http://deployingradius.com - The web site of the book http://deployingradius.com/blog/ - The blog
