The Code I used is as follows

import java.util.Enumeration;
public class SearchActive
     public static void main(String[] args)
          // rechargement de l'environnement de l'initialisation du context
          DirContext ctx = null;
          Hashtable env = new Hashtable();
          env.put(Context.INITIAL_CONTEXT_FACTORY,"com.sun.jndi.ldap.LdapCtxFactory");
          env.put(Context.PROVIDER_URL, "ldap://200.200.200.12/");
          env.put(Context.SECURITY_AUTHENTICATION,"simple");
          env.put(Context.SECURITY_PRINCIPAL,"200.200.200.12\\Administrator");
          // specify the username
     //     env.put(Context.SECURITY_CREDENTIALS,"digactive");
          // specify the password
          try {
               // Crer le context initial
               ctx = new InitialDirContext(env);
               System.out.println("8");
               SearchControls cons = new SearchControls();
               cons.setSearchScope(SearchControls.SUBTREE_SCOPE);
               NamingEnumeration answer = ctx.search("dc=exchange,dc=com","objectclass=user",cons);
               while(answer.hasMore())
                    SearchResult result = (SearchResult)answer.next();
                    Attributes rattr = result.getAttributes();
                    for(NamingEnumeration ne = rattr.getAll();ne.hasMore();)
                         Attribute natt = (Attribute)ne.next();
                         String sid = natt.getID();
                         for(Enumeration vals = natt.getAll();vals.hasMoreElements();)
                              System.out.println(sid+": "+vals.nextElement());
          catch(Exception e)
               e.printStackTrace();     
Can anybody tell me where is the problem
Thanks

Hi, all
Please help me to check where is wrong for the code to access LDAP and get a user's email address.
The code is shown below.
It works before calling ctx.getAttributes, and it shows the error msg as below after calling ctx.getAttributes.
"Problem getting attribute:javax.naming.NamingException: [LDAP: error code 1 - 00000000: LdapErr: DSID-0C0905FF, comment: In order to perform  this operation a successful bind must be completed on the connection., data 0, veceFinished executing"
I don't know if the getAttributes parameter setting is wrong or the env constant setting wroong.
package com.mycompany;
import java.io.*;
import java.util.*;
import javax.naming.Context;
import javax.naming.directory.InitialDirContext;
import javax.naming.directory.DirContext;
import javax.naming.directory.Attributes;
import javax.naming.NamingException;
public class aaa
     public static void main(String args[]) throws Exception
          Hashtable env = new Hashtable();
          env.put(Context.INITIAL_CONTEXT_FACTORY,
     "com.sun.jndi.ldap.LdapCtxFactory");
          env.put(Context.PROVIDER_URL, "ldap://mycompany.com");
          env.put(Context.SECURITY_AUTHENTICATION,"simple");
          env.put(Context.SECURITY_PRINCIPAL,"mycompany.com/Administrator/");
          env.put( Context.REFERRAL, "follow" );
          try
     System.out.println("0");
          // Create the initial directory context
          DirContext ctx = new InitialDirContext(env);
     System.out.println("1");
          Attributes attrs = ctx.getAttributes("cn=andym,cn=Users,dc=mycompany,dc=com");
               System.out.println("mail: " + attrs.get("mail").get());
          catch (NamingException e)
          System.err.println("Problem getting attribute:" + e);
