title: unboundid ldap SDK how to get all users and exclude a department
body: <p>I have sample code</p>
  
  <pre><code>Filter searchFilter = Filter.create("(sAMAccountType=805306368)");
                          SearchRequest searchRequest =
                                  new SearchRequest(advanceBaseDnTxt.getText(), SearchScope.SUB, searchFilter,
                                          ldapAttributeSet);
                          SearchResult searchResult = lcon.search(searchRequest);
  </code></pre>
  
  <p>Is this enough <strong>for retreiving all users</strong> and how to exclude a department also?</p>
