title: Keeps being prompted for credentials
body: <p>What I did so far:</p>
  
  <ol>
  <li><p>Created the website with this web.config (this is just the settings part, not the entire file :) )</p>
  
  <pre><code>&lt;appSettings&gt;
  &lt;add key="webpages:Version" value="3.0.0.0"/&gt;
  &lt;add key="webpages:Enabled" value="false"/&gt;
  &lt;add key="ClientValidationEnabled" value="true"/&gt;
  &lt;add key="UnobtrusiveJavaScriptEnabled" value="true"/&gt;
  &lt;add key="autoFormsAuthentication" value="false"/&gt;
  &lt;add key="enableSimpleMembership" value="false"/&gt;
  &lt;/appSettings&gt;
  &lt;system.web&gt;
  &lt;compilation debug="true" targetFramework="4.6.2"/&gt;
  &lt;httpRuntime targetFramework="4.6.2"/&gt;
  &lt;authentication mode="Windows"&gt;&lt;/authentication&gt;
  &lt;authorization&gt;
    &lt;deny users="?"/&gt;
  &lt;/authorization&gt;
  &lt;/system.web&gt;
  </code></pre></li>
  <li><p>Created a controller:</p>
  
  <pre><code>[Authorize(Users = @"myPcName\myUserName,skynet\Simple")]
  public class AuthenController : Controller
  {
      [Authorize(Users = @"myPcName\myUserName")]
      public ActionResult ForAdministrator()
      {
          return View();
      }
      [Authorize(Users = @"myPcName\Simple")]
      public ActionResult ForUser()
      {
          return View();
      }
  }
  </code></pre></li>
