Can (and should?) Zend_Auth return class as the Identity?

I have a class R00_Model_User, which, curiously enough, represents user as he is. Can $result->getIdentity() return me an object of this class? (Or maybe it's stupid?)

(There is a factory method in R00_Model_User which prevents from duplicating objects. I'd like Zend_Auth to use it instead of creating a new object, if it can)

Two options:

  • write your own authentication adapter subclassing the out-of-the-box-adapter that matches your scenario best

    class R00_Auth_Adapter extends Zend_Auth_Adapter_*
{
    /**
     * authenticate() - defined by Zend_Auth_Adapter_Interface.  This method is called to
     * attempt an authentication.  Previous to this call, this adapter would have already
     * been configured with all necessary information to successfully connect to a database
     * table and attempt to find a record matching the provided identity.
     *
     * @throws Zend_Auth_Adapter_Exception if answering the authentication query is impossible
     * @return Zend_Auth_Result
     */
    public function authenticate()
    {
        $result = parent::authenticate();
        if ($result->isValid() {
            return new Zend_Auth_Result(
                $result->getCode(),
                R00_Model_User::load($result->getIdentity()),
                $result->getMessages()
            );
        } else {
            return $result;
        }
    }
}

    This will allow you to code

    $adapter = new R00_Auth_Adapter();
//... adapter initialisation (username, password, etc.)
$result = Zend_Auth::getInstance()->authenticate($adapter);

    and on successfull authentication your user-object is automatically stored in the authentication storage (session by default).

  • or use your login-action to update the stored user identity

    $adapter = new Zend_Auth_Adapter_*();
$result = $adapter->authenticate();
if ($result->isValid()) {
    $user = R00_Model_User::load($result->getIdentity());
    Zend_Auth::getInstance()->getStorage()->write($user);
}

In one of my applications, I have getIdentity() return a user object, and it works pretty well for me. To use your factory method, do like this:

$auth = Zend_Auth::getInstance();
$user = R00_Model_User::getInstance(...);
$auth->getStorage()->write($user);

Then when you call getIdentity(), you will have your user object.
