Apache :: Set Up SSL Listening On Port 443 - Client Authentication

I am setting up apache 2.4 as a service locally through localhost on a windows 2008 R2 standard server. I have set up SSL listening on port 443 and works correctly, however I am having trouble figuring out how to get apache to authenticate my CAC card.

I have downloaded the DOD certs and put them into various types of files including pem, base 64, der etc and I have yet to figure out a way to get the client certificates validated.

I have left out the information about the SSLCertificateChainFile, SSLCACertificateFile and SSLCARevocationPath as I am sure this must be where my problem is.

Is it possible to get this done through localhost. Here is the error I am getting in the error log.

[Wed Oct 29 11:37:05.675491 2014] [ssl:error] [pid xxxx:tid xxx] [client 127.0.0.1:59282] AH02039: Certificate Verification: Error (20): unable to get local issuer certificate

I am using a self created self signed server ceritficate. Here are some details from my httpd-ssl.conf file:

Code:

<VirtualHost _default_:443>
DocumentRoot "${SRVROOT}/htdocs"
ServerName localhost:443

ServerAdmin admin@example.com
ErrorLog "${SRVROOT}/logs/jtdi.log"
TransferLog "${SRVROOT}/logs/jtdi-Transfer.log"
