Java获取Ldap叶子节点

Java中怎么获取Ldap的某个节点下的素有叶子节点，例如Ldap结构如下：
ou=admin
|-ou=leaf1
|-ou=leaf2
|-ou=leaf3

说明：ou=admin是一个节点，它下面有三个叶子节点leaf1、leaf2、leaf3
只提供ou=admin，怎么获取三个叶子节点？
答案准确必有加分！

使用netscape的ldap工具包。使用其它的工具包，写法类似。

注：必须知道base dn，以下假定ou=admin为base dn。若有明确的base dn，那写法比如：ou=admin,o=test1

源代码如下：
==========================
import netscape.ldap.*;

public class SearchTest {
public static void main(String[] args) {
LDAPConnection lc = null;
LDAPEntry findEntry = null;
int status = -1;
try {
// lc = ConnectionPool.

lc = new LDAPConnection();
/* Connect to server */
String MY_HOST = "localhost";
int MY_PORT = 389;
lc.connect(MY_HOST, MY_PORT);

System.out.println("1=========" +lc.isConnected());

lc.authenticate("cn=Directory Manager","password");

System.out.println("2=========" +lc.isConnected());

/* search for all entries with surname of Jensen */
String MY_FILTER = "(objectclass=*)";
String MY_SEARCHBASE = "ou=admin";

LDAPSearchConstraints cons = lc.getSearchConstraints();
cons.setBatchSize(0);
cons.setMaxResults(5);

MY_FILTER = "(objectclass=*)" ;

LDAPSearchResults res = lc.search(MY_SEARCHBASE,
LDAPConnection.SCOPE_ONE,
MY_FILTER,
null,
false,
cons);

while (res.hasMoreElements()) {
LDAPEntry cLDAPEntry = res.next() ;
System.out.println("" + cLDAPEntry.getDN());
System.out.println("" + cLDAPEntry.toString());

}
status = 0;
} catch (LDAPException e) {
System.out.println("Error: " + e.toString());
e.printStackTrace();
}

/* Done, so disconnect */
if ((lc != null) && lc.isConnected()) {
try {
lc.disconnect();

System.out.println("3=========" +lc.isConnected());

} catch (LDAPException e) {
System.out.println("Error: " + e.toString());
}
}

System.out.println("4=========" +lc.isConnected());

System.exit(status);
}
}
