Some old posts on designing a single sign-on system with OAuth 2. They may not have been in the ones I sent to Justin. http://www.thread-safe.com/2012/02/designing-single-sign-on-system-using.html http://www.cloudidentity.com/blog/2013/01/02/oauth-2-0-and-sign-in-4/
Are you wanting something more like these with the info on how you could do it with OAuth 2? John B.
