Presentation: Security (CAS and OpenID) with Ruby

Bookmarks
In this presentation from QCon SF 2007, Justin Gehtland explains two open solutions to distributed identity and their Rails integration components: the OpenID system (using ruby-openid) and CAS (using rubycas-client).

The presentation gives a good introduction to authentication and the options available today, particularly for Ruby. With systems like OpenID or CAS, it's possible to delegate the task of authenticating a user (ie. letting the user log in). Instead of writing code for authentication, OpenID and CAS servers handle everything involved. The presentation also shows how to install these servers, which is useful for companies that want to keep the authentication server internal.

For a overview of how to get started with these technologies, Justin shows how to develop for both OpenID and CAS and builds three applications using these systems.
