title: Can I add Active Directory properties to be loaded in UserPrincipal?
body: <p>Using the DirectorySearcher we can specify which properties can be loaded when searching in the AD. </p>
  
  <pre><code>    DirectorySearcher dsLookForDomain = new DirectorySearcher(deBase);
      dsLookForDomain.PropertiesToLoad.Add("msDS-PrincipalName"); 
  </code></pre>
  
  <p>I'm interested in loading <strong>msDS-PrincipalName</strong> property. Is this possible?</p>
