Hello

I've got a problem with my eap-tls configuration : the server is accepting the device (  rad_check_password: Auth-Type = Accept, accepting the user), but it doesn't connect to the to access-point (HP Procurve). The server is a virtual Suse linux enterprise and the client is windows XP sp 3.

Any help would be great....

Here is the output on the server:
