Hi Again, This email refers to the earlier email sent with the subject "EAP/TLS Configuration". After having some trouble with the Windows XP and freeRADIUS, I was able to connect to the AP. But, in the configuration (Windows XP), I removed the check mark at 'Validate Server Certificate'. Then, suddenly, it started working. Anybody knows the reason for this? Further, after establishing the connection, I terminated the connection (by disabling the network connection). Then, I tried to connect again (by enabling). But, this time, the user machine connected to the AP automatically (without asking for the credentials.). It seems like something has cached these entries. Anybody knows how to clear this cache?
