Hi, I've a problem regarding the clean disconnect of a client and some caching mechanisms. I briefly illustrate my problem : My system is composed by freeradius and chillispot with WPA enterprise (LDAP as backend). When i connect a client 1 to my system all works fine, except for the time taked by authentication process, i'm using WinXP SP2 build-in supplicant. (How I can speed up this procedure?Could you suggest me some opensource supplicant?) The problem is that when I disconnect client 1 from my system (just connecting my client to another network) and then i reconnect client1 to the system the WPA authentication failed for about 10 minutes.After this time authentication of client 1 works fine. So I think that this fact is caused by some cache mechanism used by freeradius. How can I make sure that a Client is disconnected in clean way and remove his session after it has disconnected inside Freeradius? Thanks for attention Regards, Josh
