title: LDAP SearchResult does not contain user properties
body: <p>I'm using <code>DirectorySearcher.FindOne()</code> method.</p>
  
  <p>I have specified <code>Mobile</code> number in my Active Directory user properties. My search filter looks like this </p>
  
  <pre><code>(&amp;(ObjectClass=User)(mobile=+11111111111))
  </code></pre>
  
  <p>With this filter I'm able to get appropriate user. </p>
  
  <p>I've also specified Fax number in my AD user properties, but <code>SearchResult</code> does not contain Fax property. In fact <code>SearchResult</code> contain only one property, but I'm expecting all of user properties returned, including fax number.</p>
  
  <p>Should I modify my query to get fax number returned? Maybe changes to my AD user or LDAP server required?</p>
