title: How can I get a list of Organizational Units from Active Directory?
body: <p>I've looked into the <a href="http://msdn.microsoft.com/en-us/library/system.directoryservices.aspx" rel="noreferrer">DirectoryServices</a> class and it seems to be what I need, but I can't seem to find the classes/methods needed to fetch a collection of Organizational Units.</p>
  
  <p>Can you guys give some suggestions?</p>
