title: Simple custom roles for windows authentication in asp. net?
body: <p>At our company network, the roles in Active Directory(AD) are not appropriately assigned for my application. So I created a simple table in my database mapping all the users in the AD and their roles. There is literally only two columns in this table, user and role. </p>
  
  <p>I hope to take advantage of the powerful role management in asp.net, I want to use features like <code>[Authorize(Roles = "Managers")]</code>.  is there a simple way to use these custom roles without setting up complicated role and membership provider? </p>
  
  <p>application background: 
  sql server, linq, asp.net mvc </p>
