We are using FreeRadius to authenticate wireless clients. For some reason all clients are being reauthenticated every 6 minutes.
I'm not positive that FreeRadius is the culprit causing the reauth, but the only other thing it could be is the hardware's settings. For sure, the hardware has a setting to Reauthenticate ever nn minutes. Setting this to 0 is supposed to disable reauthentication. But, not matter what I set it for (0-65535) I get reauthentication every 6 minutes. The hardware manufacturer has done testing and say they have ruled out a problem on their end. ;)
Are you sending a Session-Timeout attribute (with a value of 60*6=360) back to the access point with the Access-Accept? We use this feature to force re-authentication after a fixed interval.
