 try {
     LdapContext ctx = new InitialLdapContext(
       env, null);
                 
     // Create "extended" operation to use
     ExtendedRequest req = new GetTimeRequest();
     
     // Perform the operation
     GetTimeResponse response = (
       GetTimeResponse) ctx.extendedOperation(req);
 } catch (NamingException e) {
 }
