stale session

[Sergio Diaz]

I have a FreeRADIUS Version 2.1.12 with mysql db
I have APs from open-mesh with coova chilli. 

Sometimes when a user lost the connection to the AP from many reasons, the session in radacct table no have nothing in acctstoptime and the user can't login because i have enable a simultaneous-use=1 .

 is there a way to fix that? 
Radius can clean the stale session? 
Can i use other atributes like idle-timeout or session-timeout?





Saludos Cordiales,

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.

  Get the AP to send accounting packets with Acct-Status-Type = Accounting-On.  That tells the server that the AP has rebooted, and the server will clear the old sessions from the DB.

  Otherwise, FreeRADIUS has no idea that the AP rebooted, and can only assume that the sessions are still active.
