使用Java unboundid-ldapsdk查詢ldap服務器

Question

我已經使用Apache Director Studio設置了ldap服務器：

這是我的代碼：

import com.unboundid.asn1.ASN1OctetString;
import com.unboundid.ldap.sdk.*;
import com.unboundid.ldap.sdk.controls.SimplePagedResultsControl;
public class App {

      /**
       * @param args
       * @throws LDAPException 
       */
      public static void main(String[] args) throws LDAPException {


        LDAPConnection connection = new LDAPConnection("localhost", 10389, "uid=admin,ou=system","secret");//"cn=admin4directory,dc=ilex-si,dc=eu", "M3d2p5a4!");

        //SearchRequest searchRequest = new SearchRequest("ou=people,dc=ilex-si,dc=eu", SearchScope.SUB,"(ixuid=*)");
        SearchRequest searchRequest = new SearchRequest("ou=people,dc=example,dc=com", SearchScope.BASE,Filter.createEqualityFilter("objectClass", "person"));

        ASN1OctetString cookie = null;
       do
       {
         searchRequest.setControls(
              new Control[] { new SimplePagedResultsControl(500, cookie) });
         SearchResult searchResult = connection.search(searchRequest);

         // Do something with the entries that are returned.

         cookie = null;
         for (Control c : searchResult.getResponseControls())
         {
           if (c instanceof SimplePagedResultsControl)
           {
             cookie = ((SimplePagedResultsControl) c).getCookie();
             System.out.println("\ncookie = "+ cookie.toString());
           }
         }
       } while ((cookie != null) && (cookie.getValueLength() > 0));


       connection.close();

      }

    }

我想執行分頁查詢，但是使用此代碼，我返回了一個空白cookie。如何打印cn = john smit和cn robert smith值？

您是否在https://docs.ldap.com/ldap-sdk/docs/javadoc/com/unboundid/ldap/sdk/controls/SimplePagedResultsControl.html嘗試了簡單示例

確保您的SearchScope.BASE必須位於LEAST SearchScope.ONE或更好的SearchScope.SUB。

不知道暗示什么是“如何打印cn = john smit和cn robert smith值？”
