LDAPException: Invalid Credentials (49) Invalid Credentials with grails

These are the imports that I am using:

import com.novell.ldap.*;
import java.io.UnsupportedEncodingException;

and I am trying to do a very simple password validation that I found at:

http://developer.novell.com/documentation开发者_Python百科/samplecode/jldap_sample/index.htm

and I can't seem to get the bind to work. Does anyone have a better way of doing this with grails or java. I am finding myself really lost and any examples or guidance would help.

Thanks.

This Java example uses the UnboundID LDAP SDK to connect and bind to a directory server. Run it like:

$ java -cp YOUR_CLASSPATH BindExample hostname port bindDn password

BindExample.java:

import com.unboundid.ldap.sdk.BindRequest;
import com.unboundid.ldap.sdk.BindResult;
import com.unboundid.ldap.sdk.Control;
import com.unboundid.ldap.sdk.LDAPConnection;
import com.unboundid.ldap.sdk.LDAPException;
import com.unboundid.ldap.sdk.ResultCode;
import com.unboundid.ldap.sdk.SimpleBindRequest;

public final class BindExample {

    public static void main(String... args) {
    if(args.length == 4) {
        final String hostname = args[0];
        final String dn = args[2];
        final String password = args[3];
        int port;
        LDAPConnection ldapConnection;
        try {
            port = Integer.parseInt(args[1]);
        } catch(NumberFormatException nfx) {
            System.err.println(args[1] + " is not an integer, using 389");
            port = 389;
        }
        try {
            ldapConnection =
                new LDAPConnection(hostname,port);
        } catch(final LDAPException lex) {
            System.err.println("failed to connect to "
                   + hostname + " " +
                   lex.getMessage());
            return;
        }
        try {
            final BindRequest bindRequest =
                new SimpleBindRequest(dn,password);
            BindResult bindResult = 
                ldapConnection.bind(bindRequest);
            if(bindResult.getResultCode() == ResultCode.SUCCESS) {
                System.out.println("authentication successful");
            }

                    bindResult.getResponseControls();
                // handle response controls ...
            }
            ldapConnection.close();
        } catch(final LDAPException lex ) {
            System.err.println("bind failed");
            ldapConnection.close();
            return;
        }
    }
  }
