authentication in zend - php

Question

I am using zend auth for authentication. and everything works fine on my local machine.
But when i try to connect to remote server for database than problem starts.
It is not able to login. Is is some problem with session or what..?
$db = new Zend_Db_Adapter_Pdo_Mysql(array(
'host' => 'localhost',
'username' => 'root',
'password' => '123456',
'dbname' => 'saet'
));
$form = new Default_Form_Login();
if ($this->getRequest()->isPost()) {
//$db = Zend_Registry::get('db');
$adapter = new Zend_Auth_Adapter_DbTable($db);
$adapter->setTableName('users')
->setIdentityColumn('username')
->setCredentialColumn('password')
->setCredentialTreatment('MD5(?)');
$credentialsArray = $this->_request->getParams();
$adapter->setIdentity($credentialsArray['username'])
->setCredential($credentialsArray['password']);
$auth = Zend_Auth::getInstance();
$result = $auth->authenticate($adapter);
if ($result->isValid()) {
$userInfo = $adapter->getResultRowObject(null, 'password');
// the default storage is a session with namespace Zend_Auth
$authStorage = $auth->getStorage();
$authStorage->write($userInfo);
$this->_helper->FlashMessenger('Successful Login');
return $this->_helper->redirector('index');
} else {
$this->_helper->FlashMessenger->addMessage(array('error',"Invalid Username/Password"));
return $this->_helper->redirector('login');
}
now when i change the db details to remote server. it fails to log in. i m new in zend. and i get application error.

To display errors change your application.ini file as follows
phpSettings.display_startup_errors = 1
phpSettings.display_errors = 1
resources.frontController.params.displayExceptions = 1
and then give us the error.
