    X.509 SSL certificate authentication plugin
    
    Add a plugin for X.509 SSL certification authentication. This is similar to
    Kerberos auth plugin. It must be used in conjunction with Apache mod_ssl.
    
    This is still a WIP patch. Need documentation and unit tests. I've tested
    in Apache and the basics seem to be working fine.
