We have consolidated the "Overview" and "Tutorials" areas into one "Guidance" area for MVC. There will be redirects to the new locations put up within the next day. You can see the old and new URLs here: http://forums.asp.net/t/2014539.aspx?ASP+NET+MVC+Content+Reorganization+10+23+2014
The content can be found under http://www.asp.net/mvc/overview. The tutorial you are looking for is now here: http://www.asp.net/mvc/overview/security/create-an-aspnet-mvc-5-app-with-facebook-and-google-oauth2-and-openid-sign-on
I apologize for any inconvenience.
