How to check whether the UID are present already. If it's present increment one value for the new user with 3 letters of first name and last name. If UId are not present Assign the value of UID ...and store in eDirectory..
public class searchattribute
{
public static void main (String[] args)
{
Hashtable env = new Hashtable();
String adminName = "cn=admin,o=novell";

//Access the keystore, this is where the Root CA public key cert was installed
//Could also do this via the command line option java -Djavax.net.ssl.trustStore....
//No need to specifiy the keystore password for read operations

if the name oof the user same so it must check in search and if the user is present it must increment its value
