We have this is a problem, too. Last Romel's solution sounds pretty good.
I would like though that this can be the default behavior (ex: putting it in AppController::beforeFilter). But I want that all the actions specified by $this->Auth->allow(...) do not to emit the {"login":true}

One option is to call $this->Auth->allow(...) before
parent::beforeFilter() in the derived controllers and having something (?) that tells if the current action is in the allow list.
However an optional solution should be able to work even if parent::beforeFilter() is called before  Auth->allow.

Should not this be a feature of the AuthComponent?

Best,
   Chris

Thank you!

This is how I have tried in the first place but it is not working. $this->RequestHandler->isAjax() is null or false, so it will never execute the conditional code.

Best regards!
