title: Windows authentication and Asp.Net Web API
body: <p>I have an Intranet application with Windows authentication based on MVC4.</p>
  
  <p>When I need the WindowsIdentity for authorization purpose in a Controller I just use</p>
  
  <pre><code> HttpContext.User.Identity
  </code></pre>
  
  <p>Now I wanted to use the new Asp.Net WebAPI for some Ajax calls. </p>
  
  <p>Is there a way to get the WindowsIdenty object in the same easy way as in an MVC Controller?</p>
