title: Get Active Directory User Information With Windows Authentication in MVC 4
body: <p>I am working on an MVC 4 intranet application and am using Windows authentication. I would like to add to the user object that the authentication method uses (@User) and get that data from active directory (such as email, phone number, etc). </p>
  
  <p>I know I can create a custom Authorize attribute and add it to the controller that all of my other controllers inherit from, but I don't know if this is the right method to do what I want. </p>
  
  <p>My end goal is simple, I want @User object to have additional properties that are populated via Active Directory. Thanks for any help you can offer.</p>
