I am a first timer !

Hi I am a first timer in this Freeradius server, i have managed to configure my server on a centos machine which is runniny Asterisk. The problem comes when i have to configure it so Windows XP machine can connect, i have followed lots and lots of tutorial i don't even remember what i did, but the proble still remains. I am not sure if i created the certificates right or what. The first error that i get is something like {mohwiti.co.za/no-password attribute} Now this is what i am getting TLS Alert write:fatal:error:unknow CA TLS accept:error in SSLv3 read client certificate B Error: rlm_eap_tls: SSL_read failed in a system call (-1), TLS session fails I don't know what that means Kind Regards
