Hello Alan, Thanks for your reply. To be more specific i can tell you my scenario. client---switch---alcatel(dhcp relay agent)---freeradius and dhcp server The dhcp relay agent is generating a circuit id which i can see in the debug output, it is a hex string beginning from 0x as well as the dhcp agent remote id is visible as a hex string. Now i am putting the username format in the alcatel as mac address and i have no problem in authenticating the client from the radius server on the basis of mac address and dhcp server is giving ip address to the client. But my goal is to authenticate my client on the basis of this circuit id which is being generated by the alcatel dhcp relay agent , and hence provide ip address to the client on from the dhcp server. As i change the username format to circuit-id in the alcatel relay agent, the authentication fails as the debug output in alcatel shows the username format implies circuit-id. I am actually implementing the Alcatel Triple Play ESM scenario(alcatel also has IES and VPLS running on it), but instead of a dslam or any other relay agent i have to use the alcatel router only as the dhcp relay agent. Also i would like to know what changes i have to make in the users file or dhcp-static file or default file or radcheck, so as to do the client authentication based on the cirucit id being generated. (I tried to make a few changes but nothing works for me). Goal is : Authentication of client from radius server on the basis of circuit id and assigning ip address to the client from the dhcp server. Thanks in advance. On Mon, Mar 10, 2014 at 10:23 AM, < freeradius-users-request@lists.freeradius.org> wrote:

The mac address was sent by the wifi controller as the calling-station-id but the question is how do I match that field against the user to authorise them?
$ man unlang
It tells you how to do if/then/else checks.
Perhaps you have a more specific question?

First, does the circuit ID show up in a RADIUS packet? If so, what attribute is it?
but the radius server doesn't accept username as circuit id, it only authenticates based on mac address of the client(i tried changing the users file), so can anyone please guide me as to what changes i have to make for this to be possible.
I'm not sure what you're trying to do, so I don't have a good answer for you.
What does debug output say? What do you think it *should* say?

Hi,
I'd like to install on FreeBSD 9.2 FreeRadius2 with MySQL
which bits of http://wiki.freeradius.org/guide/SQL-HOWTO did you follow, which bits didnt work?

Anyawyas, debug mode shows:
++[unix] returns notfound
Which is pretty definitive.
Okay, what would recommend then? And the ++[unix] returns notfound is definitive of /what/?
Since I'm setting up FreeRADIUS on my NIS master, I don't really need NIS integration, the user accounts are all in /etc/passwd (and /etc/shadow) so all I need is radiusd to check for local accounts and authenticate against them. This /should/ simplify things, but apparently I'm missing something, and something probably relatively simple. Question is, what?

Uh.... the module looks users up in /etc/passwd. What could "notfound" possibly mean?

The user isn't in /etc/passwd.

rlm_unix has a flow like this:
r = getpwnam(username) if not r: return NOTFOUND if not r.passwd or len(r.passwd) < 10: s = getspnam(username) if not s: return NOTFOUND passwd = s.passwd else: passwd = r.passwd
So, either FreeRADIUS is getting no reply to getpwnam() or it's getting an empty or "x" value for the password hash at that stage, *then* calling getspnam() and getting no value.
My NIS is rusty, but IIRC calling the getspnam() routines under NIS requires you being root? Most likely this is the problem.
PAM has a suid-root helper for this; FreeRADIUS doesn't. So one possible alternative would be to use rlm_pam, and let PAM do the work of getting at the shadow data.

Le me re-iterate. Since I've installed FreeRADIUS on my NIS master, I no longer care so much about dealing with NIS. At this stage, it's simply a matter of getting FR and rlm_unix to see and access my local user/pwd sitting in /etc/passwd and /etc/shadow. Surely, setting up Fr for that is not /that/ complicated. So, forget about NIS. That is not a problem.
So, now that I have that out of the way, it seems rlm_unix isn't able to read /etc/shadow. I'm assuming the getspnam(username) call is trying to read /etc/shadow? If so, how is the best way to fix this? I read somewhere that rlm_unix didn't need to copy the password files into a temp file with radwtmp unless there was a specific reason for it. What exactly is that all about?
