Bonjour Samdoc,
As tu encore le probleme ? (dsl pour le retard de l'intervention !)

Si cela peut t'aider, voici comment j'ai fait :

Une 1ere classe :

public class Connect {
	// Main
	public static void main(String[] args) {
		Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());
		System.setProperty("javax.net.ssl.trustStore", "e:\\ldap\\keystore");
		System.setProperty("javax.net.debug", "all");
		
		User user = new User();
		user.CreateUser("user1", "User", "Charles");
	//	user.ModifyUser("use1", "User", "Henri");
	//	user.DeleteUser("user1", "User", "Henri");
                     }
}

import javax.naming.NameNotFoundException;
import javax.naming.directory.Attribute;
import javax.naming.directory.Attributes;
import javax.naming.directory.BasicAttribute;
import javax.naming.directory.BasicAttributes;
import javax.naming.directory.DirContext;
import javax.naming.directory.InitialDirContext;

public class User {

	DirContext ldapContext;
	String baseName = ",CN=Users,DC=myServer,DC=fr";
	String serverIP = "myServer";


	public void CreateUser(String username, String surname, String givenName) {
		Hashtable ldapEnv = new Hashtable();
		ldapEnv.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
		ldapEnv.put(Context.PROVIDER_URL,  "ldap://" + serverIP + ":389");
		ldapEnv.put(Context.SECURITY_AUTHENTICATION, "simple");
		ldapEnv.put(Context.SECURITY_PRINCIPAL, "cn=Administrateur" + baseName);
		ldapEnv.put(Context.SECURITY_CREDENTIALS, "*******");

		try {
			ldapContext = new InitialDirContext(ldapEnv);


			String distinguishedName = "cn=" + username + baseName;
			Attributes newAttributes = new BasicAttributes(true);
			Attribute oc = new BasicAttribute("objectclass");
			oc.add("top");
			oc.add("person");
			oc.add("organizationalperson");
			oc.add("user");
			newAttributes.put(oc);
			newAttributes.put(new BasicAttribute("sAMAccountName", username));
			newAttributes.put(new BasicAttribute("userPrincipalName", username + "@" + serverIP));
			newAttributes.put(new BasicAttribute("cn", username));
			newAttributes.put(new BasicAttribute("sn", surname));
			newAttributes.put(new BasicAttribute("givenName", givenName));
			newAttributes.put(new BasicAttribute("displayName", givenName + " " + surname));



			boolean canCreate = false;
			// on verifie que l'attibut n'est deja pas present dans la base
			try {
				Attributes attrs = ldapContext.getAttributes(distinguishedName);
			} catch (NameNotFoundException e) {
				canCreate = true;
			}
			// si pas present
			if (canCreate){
				ldapContext.createSubcontext(distinguishedName, newAttributes);
			}
//			 si present
			else{
				System.out.println("ErrorCreate : Cet User existe deja dans la base");
			}
			ldapContext.close(); 
		}
		catch (Exception e) {
			System.out.println("create error: " + e);
			e.printStackTrace();
			System.exit(-1);
		}
	}
}
