Looking for a non-trivial 3 layered asp.net example

Question

I am looking for an example of an asp.net website(with source), implemented with 3 layer architecture and has some complexities like user authentication and user permissions, etc. .

Does anybody know such an example?

If you're favouring ASP.NET MVC (and I would suggest you should be) then Nerd Dinner (source) is one of the best examples on structuring an application.

Personally I feel that rather than focus on n-Tier/3-Tier architectures you should focus your efforts on responsibly designing web applications using principles like SOLID.
