I'm modifying an existing tomcat server to use client authentication.

I'm using a self-signed CA to sign both my server and client certificate. When testing the connection using openssl, i get the following errors:

C:\OpenSSL\bin>openssl s_client -connect wppan:8443 -cert c:\test\tc5.5\2\client
\clientCert.pem -key c:\test\tc5.5\2\client\client.key -CAfile c:\test\tc5.5\2\ca\ca.pem

My server.xml configuration settings is as follows:

    <Connector port="8443" maxHttpHeaderSize="8192"
               maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
               enableLookups="false" disableUploadTimeout="true"
               acceptCount="100" scheme="https" secure="true"
    protocol="HTTP/1.1"
      sslProtocol="TLS"
    SSLEngine="on"
    SSLCertificateFile="C:\test\tc5.5\2\server\serverCert.pem"
    SSLCertificateKeyFile="C:\test\tc5.5\2\server\serverExp.key"
    SSLVerifyClient="require"  

     
        
      />

Can u advice me where goes wrong with my settings?
