Hi,
Yes you can chain authentication.
You can try something like this:
/**
* Authenticate user
*
* @param string $login
* @param string $password
* @return boolean
*/
public function authenticate($login, $password)
{
//Default table, test for admin_user
$auth_adapter = new Adapter\DbTable($this->getAdapter());
$auth_adapter->setTableName('admin_user');
$auth_adapter->setIdentityColumn('email');
$auth_adapter->setCredentialColumn('password');
$auth_adapter->setIdentity($login);
$auth_adapter->setCredential(md5($password));
$auth = new AuthenticationService(new
Storage\Session(self::BACKEND_AUTH_NAMESPACE));
$result = $auth->authenticate($auth_adapter);
if($result->isValid())
{
//authenticate with admin user table
$data = $auth_adapter->getResultRowObject(null, 'password');
$this->setData((array)$data);
$auth->getStorage()->write($this);
return TRUE;
}
else
{
//Not working tried with user table
$auth_adapter = new Adapter\DbTable($this->getAdapter());
$auth_adapter->setTableName('user');
$auth_adapter->setIdentityColumn('login');
$auth_adapter->setCredentialColumn('password');
$auth_adapter->setIdentity($login);
$auth_adapter->setCredential(sha1($password));
$auth = new AuthenticationService(new
Storage\Session(self::BACKEND_AUTH_NAMESPACE));
$result = $auth->authenticate($auth_adapter);
if($result->isValid())
{
//authenticate with user table
$data = $auth_adapter->getResultRowObject(null, 'password');
$this->setData((array)$data);
$auth->getStorage()->write($this);
return TRUE;
}
}
//Auth failed
return FALSE;
}
