Thank You Marek
My program work fine with my own cert/private key, but give the
following error if I load with real supposed certificate at client
program.

~Error with certificate at depth: 0
   issuer = /DC=dev/DC=jwrn/CN=JWRN Development
   subject =  /DC=dev/DC=jwrn/CN=Users/CN=mon
 error 26:unsupported certificate purpose
 client2.c:67 Error Connecting SSL object
 3083613872:error:14090086:SSL routine:
SSL_SERVER_CERTIFICATE:certificate verify failed:s3_clnt.c:884;

Do you know what it means?? Client's cert format wrong ???

Please help

To find certificate and private key pair:
 $ openssl x509 -in vpn-server-crt.pem -modulus -noout
Modulus=DDACB7ED10A3AE69E7FB0320471C0C3F9C6A3BC...
 $ openssl rsa -in vpn-server-key.pem -modulus -noout
Modulus=DDACB7ED10A3AE69E7FB0320471C0C3F9C6A3BC...

To find CA and certificate pair:
 $ openssl x509 -in vpn-server-crt.pem -issuer -noout  issuer=
__issuer_information__  $ openssl x509 -in cacert.pem -subject -noout
subject= __issuer_information__

To verify certificate:
 $ openssl verify -CAfile cacert.pem vpn-server-crt.pem
 vpn-server-crt.pem: OK
