Folks, This issue is resolved, it was due to the VeriSign certs. I requested the new trial certs from VeriSign and it worked great!! The other change i made in the config file was, I commented SSLCACertificateFile and kept SSLCACertificatePath because both the settings are required only in case of SelfSigned Certs. Thanks everyone for your help. Prakash

Also, about the Virtual host logs, if the following statements point to unique files for the virtual host in question, then the errors contained in these logs refer to this virtual host only. If the statements point to a common set of files used by all hosts, then the errors reported could be for any of the hosts using the log files: ErrorLog logs/ssl-error_log TransferLog logs/ssl-access_log Best regards.

I have been able to resolve the Private key issue by installing the new Verisign certificates, but now I am running into a new issue: Error_Log has the following warning message : Session Cache is not configured [hint: SSLSessionCache] ssl-error_log has the following error message : [error] Unable to configure verify locations for client authentication I use following command to start the Apache server instead of "apachectl": ./httpd -k start -f /usr/local/apache2/conf/httpd-cob-certs.conf Here is the Virtual host configuration we have in the "httpd-cob-certs.conf" file. The only difference between this and the one we were using for self-signed is the directory location in the SSL parameters. <VirtualHost serverName:PortNumber> ProxyRequests Off SSLProxyEngine On ProxyVia On RequestHeader set Front-End-Htps "On" SSLEngine On SSLProtocol ALL SSLCertificateFile /export/home/pp/newVersignCerts/pubkey.crt SSLCertificateKeyFile /export/home/pp/newVersignCerts/key.key SSLCACertificateFile /export/home/pp/newVersignCerts/IntermediateCA.crt SSLVerifyClient require SSLVerifyDepth 1 SSLCACertificatePath /app1/webMethods6/IntegrationServer/config/certs/cas #end of setup the Require Certificate ErrorLog logs/ssl-error_log TransferLog logs/ssl-access_log ProxyPass / https://ServerName:PortNumber/ <https://ServerName:PortNumber/> ProxyPassReverse / https://ServerName:PortNumber/ <https://ServerName:PortNumber/> ProxyPreserveHost On </VirtualHost> Did you get this resolved? Private key issue has been resolved by installing the new verisign certs. If not, then what OS version and APACHE version are you running on? Its Solaris9 & Apache2 When does the error occur? When we start the Apache server with Verisign certs the warning & error messages are logged in the Error_log and ssl-error_log files. The strange thing is we dont get any issue when using self-signed certs. Did you enable logging at the Virtual host level? If so, have you looked at the logs. I m not sure, Could you tell us how do we check if logging is enabled at Virtual host level? Where can we find the log files?
