According to zend documentation you could try it like this :

//Validator declaration but the way you used it should work too.
$validator = new Zend_Validate_Db_RecordExists(
    array(
        'table' => 'users',
        'field' => 'password',
        'adapter' => $this->dbAdapter,
    )
);

if ($validator->isValid($recordToCheck)) {
    // Password exists
} else {
    // Password does not exists and we display the error message
    foreach ($validator->getMessages() as $message) {
        echo 'Password not match';
    }
} 

Hope it'll help
