This week's giveaway is in the EJB and other Java EE Technologies forum. We're giving away four copies of EJB 3 in Action and have Debu Panda, Reza Rahman, Ryan Cuprak, and Michael Remijan on-line! See this thread for details.
Thank you for the excellent question! Actually, we have an entire chapter devoted to the integration of Spring Security 3 and OpenID (you may not be aware that Spr Sec 3 uses openid4java behind the scenes, which is perfect for you!).
You may actually see this full OpenID chapter (although not formatted as nicely as the book ) on the Packt web site here: Opening up to OpenID with Spring Security. This should give you a taste of the level of technical detail that I've provided on all the subjects covered in the book.
Hope this answers your question!
