How to get Primary Group details of a user from Active Directory

Question

Hi ,
This is Viswanath. I want to know how can we retrieve the primary group of a user (Active Directory). I have searhed the entire forum but could not get the required information.
The reference link is which i have searched is : http://forum.java.sun.com/thread.jspa?threadID=581444
I got a sample .NET project where we can retrieve the primary group information :
refer to the link : http://dunnry.com/blog/DeterminingYourPrimaryGroupInActiveDirectoryUsingNET.aspx
you can download the sample project and build that in VS.NET 2003 and see the result. Please let me know if this kind of implementation is possible in java.
Kindly help me as i have to provide a solution to my client.
Regards,
Viswanath.

To connect to the Active Directory you can do something like this:
import java.util.Hashtable;
import javax.naming.Context;
import javax.naming.NamingException;
import javax.naming.directory.DirContext;
import javax.naming.directory.InitialDirContext;
public class AD
public static void main(String[] args)
Hashtable environment = new Hashtable();
//Just change your user here
String myUser = "myUser";
//Just change your user password here
String myPassword = "myUser";
//Just change your domain name here
String myDomain = "myDomain";
//Host name or IP
String myActiveDirectoryServer = "192.168.0.20";
environment.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
environment.put(Context.PROVIDER_URL, "ldap://" + myActiveDirectoryServer + ":389");
environment.put(Context.SECURITY_AUTHENTICATION, "simple");
environment.put(Context.SECURITY_PRINCIPAL, "CN=" + myUser + ",CN=Users,DC=" + myDomain + ",DC=COM");
environment.put(Context.SECURITY_CREDENTIALS, myPassword);
try
DirContext context = new InitialDirContext(environment);
System.out.println("Exit!!");
catch (NamingException e)
e.printStackTrace();
