Open Directory as a PKI

Paul Suh did a session at MacIT 2013 on Certificates, specifically in regards to Open Directory serving as a PKI.  The session was only 45 minutes long, so he could not go into great detail.  Thankfully, Paul has written a three part article that covers using an Open Directory-based PKI so that the details can be thoroughly covered.  Check out the three part article over on his blog, ps | enable.
