title: Impersonate tag in Web.Config
body: <p>I'm using <code>impersonate</code> tag in my web.config in Asp.net 4.0 website.</p>
  
  <p><strong>Below is my Web.Config code:</strong></p>
  
  <pre><code>&lt;system.web&gt;
      &lt;authentication mode="Windows"&gt;
          &lt;identity impersonate="true"                 
              userName="Administrator" 
              password="LALLA$26526"/&gt;
       &lt;/authentication&gt;
  &lt;/system.web&gt;
  </code></pre>
  
  <p>When I run app in Visual Studio I get this error:</p>
  
  <pre><code>Parser Error Message: Unrecognized element 'identity'.
  </code></pre>
  
  <p>Source Error:</p>
  
  <pre><code>Line 50:    &lt;system.web&gt;
  Line 51:        &lt;authentication mode="Windows"&gt;

  Line 53:                 userName="Administrator"
  Line 54:                 password="LALLA$26526"/&gt;
  </code></pre>
