I have setup a custom module to do auth and acct. In debug mode everything appears correct, and responses appear correct. When I don't have radius running in debug mode, responses still appear correct, but if auth fails due to simultaneous use, radius is logging 'Auth: Login OK'. Authentication was successful, but the auth request failed due to simultaneous use, so it should be logging a failure I would think. Any idea what I might be doing wrong?

The "Login OK" message is produced only when it sends an Access-Accept back to the NAS. See src/main/auth.c. If a simultaneous-use check fails, it returns Access-Reject, and logs "You are already logged in..." The debug log you posted shows it receiving no packets, and therefore doing nothing. Alan DeKok.

If simultaneous checking rejected the user you will have an entry like: Multiple logins (max 1) : [username] in radius.log. Ivan Kalik Kalik Informatika ISP
Well, in debugging mode, it doesn't log anything to the file, but the debug output shows it being rejected. When I am not running in debug, I only get 'Login OK: [zdls02/p2182111] (from client allowed_clients port 536936642)' logged by the radius server, I am logging my own simultaneous use message, although this shows up prior to the login ok message in the logs.

You authentication module is broken. ...

It first returns ok, then rejects. So you get both login OK and reject. Fix the module. Ivan Kalik Kalik Informatika ISP
The authentication portion of the module returns ok, the session portion returns reject, as it should. On Wed, Jun 17, 2009 at 9:18 AM, Ivan Kalik<tnt@kalik.net> wrote:

No. The session portion should return "ok", and increment request->simul_count. See rlm_radutmp for examples. This is because users may be tracked in multiple places (radutmp, sql, etc.), *and* they have have Simultaneous-Use limits that are more than one. This allows the SQL module to say "I track one login", and the radutmp module to say "I track a different login", with the admin allowing 2 simultaneous logins. Alan DeKok.
Ah yes, I was doing that wrong, that seems to work much better now. Thank you. On Wed, Jun 17, 2009 at 10:28 AM, Alan DeKok<aland@deployingradius.com> wrote:
