The only thing that i can see that worth the concern is using  $this
->params['form']['username'] and also $this->User->query() , its been
clearly stated in the cook book that using "query" instead of "find" will
make you go with your own to prepare the SQL statement that you wish to
execute, i would recommend using $this->data instead of $this->params and
also using $this->User->find instead of $this->User->query to stay in the
safe side.
