Here is the configuration I'm using that works:

The only thing not here is the following (which is in another part of the
configuration file):
SSLCACertificateFile /etc/httpd/conf/ssl.calist
That file contains the CA Certificate (of my self-created CA) so Apache
can authenticate the client certificates. I used TinyCA to create all the
appropriate certificates. I did pull a bunch of settings from the ssl
portion of the default configuration and put them here so I had everything
in one place for easy testing.
