I want to do some stuff in the users/login action before login user.
For example i have captcha code on each 3rd submit of the login form and i want to check if the captcha code is valid. If it is not valid i want user to fill it up correctly first, before is able to submit. And if captcha is ok i want to use Auth->login()
Unfortunately when submit the form Auth->data['User']['username'] and Auth->data['User']['password'] are filled and the login is done behind(automagically)...
How can i disable automagically user login of the Auth component and do that only from Auth->login($data)?
