[KamranShahid]

tried with

var client = new Client("cn=developer,dc=shihadeh,dc=intern", "shihadeh.intern", "developer_pass", "LDAP//localhost:389"); but always getting ldap server not available

Same server when i tried to access via java code then it is binding

 public static void main(String[] args) {
        String url = "ldap://localhost:389";
        Hashtable env = new Hashtable();
        env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
        env.put(Context.PROVIDER_URL, url);
        env.put(Context.SECURITY_AUTHENTICATION, "simple");
        env.put(Context.SECURITY_PRINCIPAL, "cn=developer,dc=shihadeh,dc=intern");
        env.put(Context.SECURITY_CREDENTIALS, "developer_pass");

        try {
            DirContext ctx = new InitialDirContext(env);
            System.out.println("connected");
            System.out.println(ctx.getEnvironment());

            // do something useful with the context...

            ctx.close();

        } catch (AuthenticationNotSupportedException ex) {
            System.out.println("The authentication is not supported by the server");
        } catch (AuthenticationException ex) {
            System.out.println("incorrect password or username");
        } catch (NamingException ex) {
            System.out.println("error when trying to create the context");
        }
    System.console().readLine();
    }
