Again, no expert here, but as I understand it you simply "plugin" your auth process/module (Travis_Auth) to an existing FR Auth method. Travis_Auth does whatever logic you wish and returns Accept, Reject, OK, whatever - I'm not sure what the return option are or NEED to be.
In your case I THINK you'd mess with the eap.conf and / or inner-tunnel. Those are setup to handle anything that uses EAP stuff, which I assume your WPA2 gear will use? We use the "WPA2-Enterprise" for our Aruba wireless, and it uses NTLM_AUTH as the backend auth method. Works good so far. Some day I'll get it integrated with LDAP for DVLANs, HOPEFULLY....

The term 'listener' is specific to what I was trying to accomplish with JRadius. I also neglected to mention the important fact that I need to accomplish authentication specifically for WPA2, but without using ntlm_auth etc. I basically want the ability to say "yes" or "no" to a WPA2 user based on rules that I define, hence my looking at rlm_perl and rlm_jradius, both let me write something of my own. However, to use either of those with WPA2, I imagine I have to follow the 4-way handshake properly, or the supplicant will bark? I realize that this is stepping a bit outside the realm of just freeRadius, but if anyone has information it would be extremely helpful. -Travis From: freeradius-users-bounces+tdimmig=impulse....@lists.freeradius.org [mailto:freeradius-users-bounces+tdimmig=impulse....@lists.freeradius.org] On Behalf Of Gary Gatten Sent: Wednesday, February 23, 2011 3:24 PM To: 'FreeRadius users mailing list' Subject: RE: non-standard authentication I'm CERTAINLY no expert in this, but I can hopefully point you in the right direction. There is some doc within the FR install (and the Wiki I think) about writing your own "modules" - I think this is what you want. Although, I think you can do pretty much anything with rlm_perl and unlang, but nonetheless - yes, you can write your own auth module. I don't thik it would be a separate "listener", but just another module FR uses to auth RADIUS requests. Ie: instead of FR using RLM_LDAP, EAP, unix, ntlm_auth, etc. - it would use "Travis_Auth". Not sure if that helps. If you can't find doc on "modules" LMK and I'll see if I can track it down for you. From what I remember it's not rocket science, but not trivial either.

I am looking into using either rlm_perl or (preferably) rlm_jradius to be able to write my own piece to do authentication. I believe this is possible with either module (please correct me if I'm wrong on that, it would stop me in my tracks). What I need to know is if when writing my own authenticator there is a terribly complicated process of requests and responses that I have to honor in order to make the supplicant happy, or if I can trivially accept or reject based on the parameters of my business problem. As a test case, I wrote a Java class for rlm_jradius that just replaced reject packets with accept packets, to see if it would work. I found that if I hooked into it at the 'post_auth' stage it didn't matter what my reply was, freeRadius remembered that auth had failed and stripped all the attributes from the response packet. That was long winded, here is a summary of my questions. Can I write my own piece to do authentication? Where in the freeRadius process do I list that listener? Is there a series of requests and responses that I have to honor? -Travis "This email is intended to be reviewed by only the intended recipient and may contain information that is privileged and/or confidential.
