title: Authentication issue when debugging in VS2013 - iis express
body: <p>I'm trying to pick up the windows username when debugging in Visual Studio 2013. I am simply using:</p>
  
  <pre class="lang-cs prettyprint-override"><code>httpcontext.current.user.identity.name
  </code></pre>
  
  <p>If I run this on my Dev Server it works fine, if I run it in debug mode on any previous version of Visual Studio it also works fine.</p>
  
  <p>My problems is - If i run this on visual studio 2013 I get an empty string.</p>
  
  <p>My web config is as follows.</p>
  
  <pre class="lang-xml prettyprint-override"><code>&lt;system.web&gt;
      &lt;authentication mode="Windows"/&gt;
      &lt;identity impersonate="false"/&gt;
      &lt;authorization&gt;
         &lt;allow users="*"/&gt;
      &lt;/authorization&gt;
      &lt;compilation debug="true" strict="false" explicit="true" targetFramework="4.0"/&gt;
      &lt;customErrors mode="Off"/&gt;
  &lt;/system.web&gt;
  </code></pre>
