Hi folks: I'm still trying to configure any authentication method that includes a client certificate validation (PEAP, EAP-TTLS... ) behind my window-vista supplicant software client, but unfortunately no successfully. Attached to this mail is the output of one PEAP try. The authentication starts once and again forever, in a loop, but never ends successfully. I have verify that the client certificate include the Microsoft extensions # openssl x509 -text -in client.pem X509v3 extensions: X509v3 Extended Key Usage: TLS Web Client Authentication and also... I have signed certificates by using the Makefile from version 2.1.8 (latest one) I'm a bit frustrated with this "certificates" locking point. Thanks a lot in advance for your help. Regards, Fernando.
