client authentication - error message included

[Samy Thiyagarajan]

Thanks  for ur response..

the error messages of client and server are follows..

client :
error:14094418:SSL routines:SSL3_READ_BYTES:tlsv1 alert unknown ca:s3_pkt.c:1052:SSL alert number 48

server:
error:140890B2:SSL routines:SSL3_GET_CLIENT_CERTIFICATE:no certificate  returned : s3_srvr.c:2015


in my s_client call i correctly specified the CAfile path.
S_client  -connect ip:port  -cert clientcert.pem  -key clientPrivKey.pem  -CAfile  /../../demoCA/cacert.pem

so is the client not able to locate the CAfile ..? if yes i wonder why?
Do I need to explicitly define somewhere in my server program that this CA is trusted..?

Awaiting for the suggestions
