Invalid Credentials

Question

Hi LDAP Gurus,
I'm a novice in LDAP and JNDI.i installed OPENLDAP on my linux system and its working fine but when i try the example of JNDI, it is giving me the error of INVALID_CREDENTIALS. The Error is :
javax.naming.AuthenticationException: [LDAP: error code 49 - Invalid Credentials]
The JNDI code is:
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;
import javax.naming.NameAlreadyBoundException;
import javax.naming.directory.*;
import java.util.*;
public class MakeRoot {
final static String ldapServerName = "10.10.10.38:389" ;
final static String rootdn = "cn=Manager, o=jndiTest";
final static String rootpass = "secret";
final static String rootContext = "o=jndiTest";
public static void main( String[] args ) {
Properties env = new Properties();
env.put( Context.INITIAL_CONTEXT_FACTORY,
"com.sun.jndi.ldap.LdapCtxFactory" );
env.put( Context.PROVIDER_URL, "ldap://" + ldapServerName + "/" );
               //env.put(Context.SECURITY_AUTHENTICATION, "simple");
     env.put( Context.SECURITY_PRINCIPAL, rootdn );
          System.out.println("Harry");
env.put( Context.SECURITY_CREDENTIALS, rootpass );
try {
// obtain initial directory context using the environment
DirContext ctx = new InitialDirContext( env );
// now, create the root context, which is just a subcontext
// of this initial directory context.
ctx.createSubcontext( rootContext );
} catch ( NameAlreadyBoundException nabe ) {
System.err.println( rootContext + " has already been bound!" );
} catch ( Exception e ) {
System.err.println( e );
I'm badly stuck. can anyone help me out of this... Thanks in advance.

I am also brand new to Java and JNDI, but here is a sample program that I wrote yesterday that seems to be working.
import java.util.*;
import javax.naming.*;
import javax.naming.directory.*;
public class bind_jndi {
public static void main(String[] args) {
int numberOfArgs = args.length;
if (numberOfArgs!=3) {
System.out.println("Invalid number of parameters\n");
System.out.println("Usage is : bind_jndi ldap_url bindDN password\n");
System.out.println("Where:");
System.out.println(" ldap_url : The LDAP Server to communicate with\n");
System.out.println(" bindDN : The DN to perform the bind with\n");
System.out.println(" password : The password for the above DN\n");
System.out.println("Ex: bind_jndi ldap://localhost:389 cn=userid pswd");
return;
System.out.println("Starting...");
// Set up the environment for creating the initial context
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
env.put(Context.PROVIDER_URL, args[0]);
// Specify the LDAP protocol version
env.put("java.naming.ldap.version", "3");
// Valid values are 'simple' and 'none'
// 'simple' -> Use clear-text password
// 'none' -> No auth, anonymous
// If the client does not specify any authentication environment
// properties, then the default authentication mechanism is "none".
// The client will then be treated as an anonymous client.
// If the client specifies authentication information without explicitly
// specifying the Context.SECURITY_AUTHENTICATION property, then the
// default authentication mechanism is "simple".
env.put(Context.SECURITY_AUTHENTICATION, "simple");
// Authenticate as Mitch and password "mysecret"
env.put(Context.SECURITY_PRINCIPAL, args[1]);
env.put(Context.SECURITY_CREDENTIALS, args[2]);
try {
// Initiate a bind, if it fails, the 'catch' will print an error
DirContext ctx = new InitialDirContext(env);
System.out.println("Authentication passed");
// Close the connection
ctx.close();
} catch (NamingException e) {
System.err.println("Authentication failed");
String err = e.getExplanation();
System.err.println("Extended message " + err);
Hope this helps.
