title: Get List of Users From Active Directory In A Given AD Group
body: <p>I have code that searches for all users in a department:</p>
  
  <pre><code>string Department = "Billing";
  DirectorySearcher LdapSearcher = new DirectorySearcher();
  LdapSearcher.PropertiesToLoad.Add("displayName");
  LdapSearcher.PropertiesToLoad.Add("cn");
  LdapSearcher.PropertiesToLoad.Add("department");
  LdapSearcher.PropertiesToLoad.Add("title");
  LdapSearcher.PropertiesToLoad.Add("memberOf");
  LdapSearcher.Filter = string.Format("(&amp;(objectClass=user)(department={0}))", Department);
  SearchResultCollection src = LdapSearcher.FindAll();
  </code></pre>
  
  <p>What would the filter need to look like if I only wanted everyone in the "Manager Read Only" AD Group? </p>
  
  <p>Am I going about this all wrong?</p>
