package com.ldap;

import java.util.Hashtable;

import javax.naming.Context;
import javax.naming.NamingEnumeration;
import javax.naming.NamingException;
import javax.naming.directory.Attribute;
import javax.naming.directory.Attributes;
import javax.naming.directory.DirContext;
import javax.naming.directory.InitialDirContext;
import javax.naming.directory.SearchControls;
import javax.naming.directory.SearchResult;

public class ConnectLdap {

	public static void main(String[] args) {

		Hashtable<String, String> env = new Hashtable<String, String>();
		env.put(Context.INITIAL_CONTEXT_FACTORY,"com.sun.jndi.ldap.LdapCtxFactory");
		env.put(Context.PROVIDER_URL, "ldap://domainName:389");
		env.put(Context.SECURITY_PRINCIPAL, "domainName\\userid");
		env.put(Context.SECURITY_CREDENTIALS, "password");

		DirContext ctx = null;
		NamingEnumeration results = null;
		try {
			ctx = new InitialDirContext(env);

			SearchControls controls = new SearchControls();
			controls.setSearchScope(SearchControls.ONELEVEL_SCOPE);
			// results = ctx.search("cn=users,DC=domain,DC=companyname,DC=com",
			// "(objectclass=top)", controls);
			results = ctx.search(
					"ou=Associates,DC=domain,DC=companyname,DC=com",
					"(objectclass=top)", controls);
			int count = 0;
			while (results.hasMore()) {
				SearchResult searchResult = (SearchResult) results.next();
				Attributes attributes = searchResult.getAttributes();
				// System.out.println(attributes+"\n");

				Attribute samaccountname = attributes.get("samaccountname");
				if (samaccountname != null) {
					String cn = (String) samaccountname.get();
					System.out.println("Count = " + count++);
					System.out.println("samaccountname = " + cn);
				}

				Attribute mail = attributes.get("mail");
				if (mail != null) {
					String cn = (String) mail.get();
					System.out.println("mail id = " + cn + "\n");
				} else {
					System.out.println("mail id = \n");
				}

				/*
				 * Attribute mailnickname = attributes.get("mailnickname"); if
				 * (mailnickname!=null) { String cn = (String)
				 * mailnickname.get(); System.out.println("mailnickname = " +
				 * cn); }
				 */

			}
		} catch (NamingException e) {
			throw new RuntimeException(e);
		} finally {
			if (results != null) {
				try {
					results.close();
				} catch (Exception e) {
				}
			}
			if (ctx != null) {
				try {
					ctx.close();
				} catch (Exception e) {
				}
			}
		}
