Zend Framework 2 Authentication with DbTable adapter

Question

That is my local.php config:

'db' => array(
    'driver' => 'pdo_mysql',
    'dns' => 'mysql:dbname=xxxx;host=localhost;',
    'username' => 'xxxx',
    'password' => 'xxxx',
    'port' => 3306,
    'charset' => 'UTF8',
    'driver_options' => array(
        PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES \'UTF8\''
    ),
),
'service_manager' => array(
    'factories' => array(
        'Zend\Db\Adapter\Adapter' => 'Zend\Db\Adapter\AdapterServiceFactory',
    )
)

And that is my authentication code:

$authAdapter = new AuthAdapter($sm->get('Zend\Db\Adapter\Adapter'));
            $authAdapter->setTableName('users')
                ->setIdentityColumn('username')
                ->setCredentialColumn('password')
                ->setCredentialTreatment("SHA2(CONCAT({$salt}, ?, salt), '512') AND active = 1");

            $authAdapter->setIdentity($formData['username'])
                ->setCredential($formData['username']);

But when I try to submit login form, zend framework throw this errors:

File: /var/www/app/vendor/zendframework/zend-authentication/src/Adapter/DbTable/AbstractAdapter.php:331
Message: The supplied parameters to DbTable failed to produce a valid sql statement, please check table and column names for validity.

Answer 1

When I debug Pdo Driver Adapter I found where is my problem.
The first problem was in that order:

'dns' => 'mysql:dbname=xxxx;host=localhost;'

it must be so :

'dsn' => 'mysql:dbname=xxxx;host=localhost;'

And the second problem was in that order:

->setCredentialTreatment("SHA2(CONCAT({$salt}, ?, salt), '512') AND active = 1");

it must be so:

->setCredentialTreatment("SHA2(CONCAT('{$salt}', ?, salt), '512') AND active = 1");
