[fw-mvc] problem in Zend_Auth_HTTP

hey alll :)

i want to use this on my AdminController.php
so in public init() i wrote this :

$config = array(
'accept_schemes' => 'basic digest',
'realm' => 'My Web Site',
'digest_domains' => '/members_only /my_account',
'nonce_timeout' => 3600,
);
$adapter = new Zend_Auth_Adapter_Http($config);

$basicResolver = new Zend_Auth_Adapter_Http_Resolver_File();

$basicResolver->setFile(APPLICATION_PATH.'\basicPasswd.txt');

$adapter->setBasicResolver($basicResolver);

$adapter->setRequest($this->_request);

$adapter->setResponse($this->_response);

$result = $adapter->authenticate();

if (!$result->isValid()) {
throw new Zend_Exception("You Dont have access to admin area");
} else {
die('u have access');
}

*and in my password file :
admin:827ccb0eea8a706c4c34a16891f84e7b

*the above pass is md5 of '12345'

the problem is it request for password again and again also when u type
the correct user password.
:(

i think it cannot match the userpass from password file
how to fix it?
