Hello everybody, I am using freeradius-1.0.4. In my situation, user "testuser" from domain "domain" logged from NAS 192.168.1.68, After a while,user "testuser" logged out,but the NAS did not send Accout-Stop packet(for some reason) and freeradius still thought that user "testuser" is alive,but Actually user "testuser" has logged off. I have set the Simulate-Use to 1 and now "testuser" can not log in any more from anywhere. I use radwho and it output as follows: # ./radwho -R User-Name = "testuser@domain" Acct-Session-Id = "02022911" NAS-IP-Address = 192.168.1.68 NAS-Port = 98335 Service-type = Login-User Framed-IP-Address = 0.0.0.0 Acct-Session-Time = 4112 Calling-Station-Id = "00d0-5926-e3fb" I want to do something to make freeradius to believe that user "testuser" is not alive,but do not konw how to do.Is there a way to solve the problem? Thanks!
