ASP.NET4

Hi I am developing an ASP.NET MVC4 social networking application which will be having 5 types of users namely student, administrator, supervisor, providers, etc. I want to use forms authentication as it is a internet application. My database has USERS, ROLES & FEATURES tables along with other tables in SQL server.
How do I implement the authentication in ASP.NET MVC?
Where do I store the logged in user's information? (e.g. session, viewbag, tempdata, etc.) and what would be the best approach to implement this? I do not want to use default websecurity feature provided by MVC.

Kindly help me on this.
Thanks in advance.
