A new SDN article, Integrating Applications With OpenSSO, starts by describing the architecture of OpenSSO's secure login process, followed by the four ways in which to manage applications' Web access. The four ways are the Policy Agent, a reverse proxy, the client SDK, and identity services. Even though identity services require extra programming, you save cycles since no other components (Policy Agent and so forth) are involved. The article then explains the three basic tasks required for setting up authentication with identity services. A demo of the steps follows, complete with code segments in a Ruby on Rails sample application.
