Hello, I am using a certificate from incommon for eap/peap setup. It works with Windows 7 when validate certificate is enabled but not with Windows XP. Windows XP works only without the certificate validation. Following is the error that I am getting with Windows XP system: [eap] processing type peap [peap] processing EAP-TLS [peap] eaptls_verify returned 7 [peap] Done initial handshake [peap] <<< TLS 1.0 Alert [length 0002], fatal bad_certificate TLS Alert read:fatal:bad certificate TLS_accept:failed in SSLv3 read client certificate A rlm_eap: SSL error error:14094412:SSL routines:SSL3_READ_BYTES:sslv3 alert bad certificate SSL: SSL_read failed inside of TLS (-1), TLS session fails. Do we need to do something special for Windows XP systems? Thanks in advance, Angela
