title: How do I plug a custom roles manager into the AuthorizeAttribute?
body: <p>I have an older database schema that I cannot change. It has a single user table with an integer field to designate user level where 1 is standard user and 5 is administrator. I'm writing an MVC front end and I want to use ASP.NET Identity. I've figured out everything else from research and the boilerplate code. I can't seem to figure out how to create a custom roles system. I realize it has something to do with implementing a role manager and role store. That's fine but how do I then connect that with MVC to get the <code>AuthorizeAttribute</code> to acknowledge my manager?</p>
  
  <p>I apologize if this is obvious but I have done my research and I'm having trouble nailing it down. </p>
