SSO Solution...Need Urgent Help

[SiahCheePing]

I dunno if I'm posting in the correct forum but I need urgent help. I'm currently a student doing my final year project in school. I've been task to come up with a prototype/solution for a Single Sign On(SSO). I've been researching for about 3 weeks now but I can't really comprehend solutions found on the web. I currently have 2 computers to work with, software available readily on hand are Windows Server 2008, SQL Server 2008 developer edition, visual studio 2008. I'm only familiar in VB.NET and SQL Database codes and basic java codes. Can any kind souls be able to help me a by explaning step-by-step solution on how I should do it because my programming is weak too. I have not started anything yet because I'm still in confusion. My project work time is only left with 3 months, what is the best and easy open source development for SSO? Suppose to be able to sign in to multiple web application on different servers using active directory for authentication.

Google's login solution is considered a single sign-on for all Google services/products.

OpenID is a more general solution, but is able to interact with a variety of products/services.

In terms of programming, you basically need a username/email, password, and any other profile information you wish to share between services. Then, you'll need bridges between the sign-on service and the 3rd-party services.

Beyond that...you'll have to do some research and probably ask your teacher/professor for more clarification.
