Dunno why but I can't post in the original thread.

original thread=> " new auth component in cake 1.2 "
http://groups.google.com/group/cake-php/browse_frm/thread/f2d0143c2e5...

My 2 cents about the new Auth component (Cake 1.2.0.5146alpha)

It stores encrypted passwords in the DB when you add/edit a new user.

Let's start with the users controller:

--------------------------------------------------------------------------- --------------------------
users_controller.php
--------------------------------------------------------------------------- --------------------------
<?php
class UsersController extends AppController {

var $name = 'Users';
var $helpers = array('Html', 'Form', 'Session');
var $components = array('Auth', 'Session');

function beforeFilter()
{
//actions we allow without authentication, you can also put
them in the app_controller.php
$this->Auth->allow('index', 'register', 'login', 'logout');
}

}
}
else
{
$this->set('auth_msg', 'Please enter your username and
password');
}
}

}

function logout()
{
$this->Session->destroy('user');
$this->Session->setFlash('You\'ve successfully logged out.');
$this->redirect(array('action'=>'login'), null, true);
}

--------------------------------------------------------------------------- --------------------------
MODEL-> user.php
the model has just a particular function (see below) that you must add
--------------------------------------------------------------------------- --------------------------
function validLogin($data)
{

$user = $this->find(array('username' => $data['User']
['username'], 'password' => ($data['User']['password'])), array('id',
'username', 'password'));
if(!empty($user)){
$this->user = $user['User'];
return TRUE;
}
else {
return FALSE;
}

}

--------------------------------------------------------------------------- --------------------------
DB table users
--------------------------------------------------------------------------- --------------------------
CREATE TABLE `users` (
`id` int(10) NOT NULL auto_increment,
`username` varchar(250) NOT NULL default '',
`password` varchar(50) NOT NULL,
`name` varchar(255) default NULL,
`email` varchar(250) NOT NULL default '',
`created` datetime NOT NULL default '0000-00-00 00:00:00',
`modified` datetime NOT NULL default '0000-00-00 00:00:00',
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;

--------------------------------------------------------------------------- --------------------------
VIEW->login.ctp
--------------------------------------------------------------------------- --------------------------
<h1>Log In:</h1>
<?= isset($auth_msg) ? $auth_msg: ''?>
<?php e($form->create('User', array('action'=>'login')));?>
<?php echo $form->input('username');?>
<?php echo $form->input('password',
array('value'=>''));?>

--------------------------------------------------------------------------- --------------------------

Enjoy and let me know if you have better ways for authentication.

I thought AuthComponent handled user login and logout on its own,
validating username/password pairs and thus I saw no reason to use a
validLogin function on the model as you did.

But: AuthComponent won't log me in with an invalid password for a
given username, but what is freaking me out is that it logs me in with
any username/password combination (even both blanks) that are not in
the database... incidentally, it logs me in with a user id of '1',
which means I turn into admin without even specifying a name or
password.

So, I'm damn sure I'm missing some very crucial information on how
AuthComponent is supposed to be used. Could anyone tell what am I
doing wrong?

My users controller:

<?php

class UsuariosController extends AppController {

var $name = 'Usuarios';

function login() {

$user_id = $this->Auth->user('id');
if (!empty($user_id) && $this->Session->valid()) {
$this->Session->setFlash(__('Already logged in',
true), 'message', array('class' => 'error'));
$this->redirect('/');
exit();
}

if (!empty($this->data)) {
if (!$this->Auth->login($this->data)) {
$this->Session->setFlash(__('Login failed', true),
'message', array('class' => 'error'));
} else {
$this->flashRedirect(__('Welcome', true), '/');
}
}
}

function logout() {
$this->Auth->logout();
$this->flashRedirect(__('Logged out', true), '/');
}

}

And App Controller:

<?php

class AppController extends Controller {

var $components = array('Session', 'Acl', 'Auth');
var $helpers = array('html', 'javascript', 'form', 'head');

function beforeFilter() {
if (isset($this->Auth)) {
$this->Auth->fields = array('username' => 'email',
'password' => 'password');
$this->Auth->userModel = 'Usuario';
$this->Auth->loginAction = array('controller'=>'usuarios',
'action'=>'login');
$this->Auth->loginRedirect =
array('controller'=>'usuarios', 'action'=>'index');
}
parent::beforeFilter();
}

function flashRedirect($message, $url = array(), $class = 'info')
{
$this->Session->setFlash($message, 'message', array('class' =>
$class));
$this->redirect($url);
exit();
}

}

The user login view:

<?=$form->create('Usuario', array('action'=>'login'))?>
<?=$form->input('Usuario.email')?>
<?=$form->input('Usuario.password', array('type'=>'password',
'value'=>''))?>
<?=$form->submit('Entrar')?>
<?=$form->end()?>

After digging quite a bit in the AuthComponent source, I think I've
found the problem. There are still some things I don't understand, so
please feel free to correct me where I might be wrong. For example,
identify() gets called twice in a login, but I can't figure where does
the second call come from and why the passed data is different in each
call: first the POST data, then username/password fields as part of a
User array. This second call is the one logging the user even if no
username/password information was given on the login form, see code
bellow. On a side note for my previous code, it is not necessary to
call $this->Auth->login() passing it $this->data. It will use $_POST
data if nothing is specified.

The identify() function of AuthComponent (auth.php 5437 2007-07-10
16:25:23Z gwoo) will use an empty array as a condition for a model-

>find() call if any of the login fields are empty, thus finding the

first result in the database: in my case, user with id=1: the
administrator. The problematic code commented:

/* Initialize the array we are going to use as a find condition as
empty */
$find = array();
/* If *both* username and password are provided as a user object */
if (isset($user[$this->fields['username']]) && !empty($user[$this-

>fields['username']]) && !empty($user[$this->fields['password']])) {

if (trim($user[$this->fields['username']]) == '=' || trim($user[$this-

>fields['password']]) == '=') {

return false;
}
/* Set find conditions */
$find = array(
$this->fields['username'] => $user[$this->fields['username']],
$this->fields['password'] => $user[$this->fields['password']]
);
/* Else, if username is provided in POST */

} elseif (isset($user[$this->userModel . '.' . $this-
>fields['username']]) && !empty($user[$this->userModel . '.' . $this-
>fields['username']])) {

/* If both are empty (why '='?) this should return a
login failure, but the misterious (for me!) second call will ruin the
login failure */
if (trim($user[$this->userModel . '.' . $this->fields['username']])
== '=' || trim($user[$this->userModel . '.' . $this-

>fields['password']]) == '=') {

return false;
}
/* Set find conditions */
$find = array(
$this->fields['username'] => $user[$this->userModel . '.' . $this-

>fields['username']],

$this->fields['password'] => $user[$this->userModel . '.' . $this-

>fields['password']]
);
}

/* At this point, if we were working with the user array and *any* but
not both of the fields were empty, find = array( ) */
$model =& $this->getModel();
/*
$model->find(am(array(), $this->userScope), null, null, -1) will
seek:
If $this->userScope == array() the first user record,
unconditionally.
Else, the first user record that matches filtering conditions, but
ommiting the identifying information: username/password
*/
$data = $model->find(am($find, $this->userScope), null, null, -1);

/*
If there are any users on the DB, $data won't be empty, thus login
is authorized
and user is acknowledged to be the first matching the prior
conditions. In my case, user with id=1: administrator.
*/
if (empty($data) || empty($data[$this->userModel])) {
return null;

}

Now the questions are:

Q1. What is this second call to identify and where does it come
from?
Q2. Is this a bug and should be reported to trac or am I doing
something deadly wrong?

Hi Gorka - I too am having problem with this issue. I am using the
excellent tutorial by Brian as a starting point, and cake 1.2.0.5146
alpha

but the second call seems to be failing a submitted & valid login for
me:
I get-- Undefined index: password [CORE/cake/libs/controller/
components/auth.php, line 653]

and the debug SQL output is here:
SELECT `User`.`id`, `User`.`group_id`, `User`.`username`,
`User`.`password`, `User`.`email`, `User`.`firstname`,
`User`.`surname`, `User`.`created`, `User`.`modified` FROM `users` AS
`User` WHERE `email` = 'ad...@admin.org' AND `password` =
'c54a39d2599bab5dd77e0ed90cec078e64ecf10c' LIMIT 1 0 0 1 call 1

6 SELECT `User`.`id`, `User`.`group_id`, `User`.`username`,
`User`.`password`, `User`.`email`, `User`.`firstname`,
`User`.`surname`, `User`.`created`, `User`.`modified` FROM `users` AS
`User` WHERE `email` = 'ad...@admin.org' AND `password` IS NULL LIMIT
1

and then the password is NULL in the 2nd call as you can see. It then
flashes me that no valid user was ffound.

anyone can advise on this?

regards

Luke
