Hi, I am simulating the problem on what if the AP goes down (due to various reasons). I observed that user is not properly disconnected and result is stale session. When the AP is up and when the previous user tries to log in he/she gets login failed message because "Simultaneous-Use" is in effect while previous session is still ticking. I am trying to find how to detect this problem automatically. Did some google and found this http://bisagunsara.blogspot.com/2007/03/stale-wifi-sessions-and-simultaneous... Before getting my hands dirty, I want to know if this is the correct way to solve this problem in freeradius2 since the article is quite old. Or I am just missing something that needs to tweak few configs and is supported out of the box in freeradius2. It is suggested in the article that it will not work together with Simultaneous-Use enabled. I want to know how others have solved this problem. Need some suggestions Thanks -- ============================== Registered Linux User #460714 Currently Using Fedora 10, CentOS 5.3 ==============================
