How to set up an Authentication and Authorization Server?

Question

How to set up an authentication and authorization server like Google, by Cookie, and then be able to make available to ASP.NET MVC applications of the same group of web applications with the same user base?

I’ve been trying to understand that example, but uses Google to try to identify a way to create such a configuration.
But I didn’t understand how I could do my own validation and also return user data (Properties, Roles and Claims).
