In addition to the standard Apache directives needed to enable SSL, you'll need a few more before the Apache modules work as they do on scripts. Add the following directives to each vhost that will be using SSL client-side certificate authentication:
- SSLCACertificateFile /etc/ssl/clientCAs.pem
+ SSLCACertificateFile /etc/ssl/certs/mitCAclient.pem
<Location />
AuthSSLCertVar SSL_CLIENT_S_DN_Email
AuthSSLCertStripSuffix "@MIT.EDU"
</Location>
-You also need to require certificate authentication. You can either use `SSLVerifyClient required` or `SSLVerifyClient optional`. `SSLVerifyClient required` has the downside that, if visitors don't have client-side certificates, they'll get an obscure OpenSSL error. However, Safari will not present certificates to a site with `SSLVerifyClient optional` set unless the user sets up an Identity Preference. For reference, scripts.mit.edu sets `SSLVerifyClient optional`.
