How setCredentialTreatment() works in Zend Framework 1.12?

Question

Heloo I am new to Zend, I need to know how setCredentialTreatment() works. I am having salt stored for each entry in database and salt is used to encrypt password some thing like this

    sha1($password.$salt);

Can there be solution for directly concatenating query for password with salt and comparing without fetchin prior to authentication?

Thanks

Answer 2

Some thing like this:-

        $auth = Zend_Auth::getInstance();
        $authAdapter = new Zend_Auth_Adapter_DbTable(
            Zend_Db_Table::getDefaultAdapter(),
            'users',
            'username',
            'password',
            "CONCAT('$this->_salt', sha(?))"
        );
        $authAdapter->setIdentity($username)
            ->setCredential($password);
