[classlib][jndi] Bind operation has now been added to ldap service provider

[Spark Shen]

Hi all

I have implemented Ldap bind operation, and file it at
http://issues.apache.org/jira/browse/HARMONY-4928.
It now targets at version 3 ldap protocol, and only supports simple(clear
text) authentication.

The implementation for add operation is added through
http://issues.apache.org/jira/browse/HARMONY-4910.
Currently, the decode function for add operation is not yet implemented.

I will add more features for ldap service provider in the future.

Any one who is interested can verify this functionality using the following
code:

import java.io.IOException;
import java.net.UnknownHostException;

import javax.net.SocketFactory;

import org.apache.harmony.jndi.provider.ldap.BindOp;
import org.apache.harmony.jndi.provider.ldap.LdapClient;
import org.apache.harmony.jndi.provider.ldap.LdapMessage;
import org.apache.harmony.jndi.provider.ldap.LdapResult;

/**
 * This class demonstrate how to connect to and send BindRequest to Ldap
server.
 */
public class Sample {
    @SuppressWarnings("unused")
    public static void main(String[] args) throws UnknownHostException,
            IOException {
            // anonymous binds
            BindOp bind = new BindOp("cn=Coder,dc=InitialDN", "secret");

            // Initialize to your ldap server address
            LdapClient client = new LdapClient(SocketFactory.getDefault(),
                    <ldap server ip addr>, 389);

            LdapMessage response = client.doOperation(bind, null);

            System.out.println(response.getMessageId());
            LdapResult re = bind.getResult();
            System.out.println(re.getErrorMessage());
            System.out.println(re.getMachedDN());
            System.out.println(re.getResultCode());
            System.out.println(re.getReferrals());
    }
}
