authentication - CakePHP Auth Component Blanks out Password -

i have following code login view:

<?php      echo $session->flash('auth');     echo $this->form->create('user', array('action' => 'login'));     echo $this->form->input('email');     echo $this->form->input('password');     echo $this->form->end('login'); ?> 

this generates following html:

   <div id="authmessage" class="message">login failed. invalid username or password.</div>    <form id="userloginform" method="post" action="/control/users/login" accept-charset="utf-8">       <div style="display: none;"><input name="_method" value="post" type="hidden"></div>       <div class="input text required">          <label for="useremail">email</label>          <input name="data[user][email]" maxlength="255" value="" id="useremail" type="text">       </div>       <div class="input password">          <label for="userpassword">password</label>          <input name="data[user][password]" id="userpassword" type="password">       </div>       <div class="submit"><input value="login" type="submit"></div>    </form> 

app controller:

    function beforefilter()     {         $this->auth->fields = array (             'username' => 'email',             'password' => 'password'         );     } 

when attempt log in error password incorrect. here's dump of $this->data:

array (     [user] => array         (             [email] => myemail@gmail.com             [password] =>          )  ) 

i found few other similar questions on stackoverflow none of them seem have answer. know why happening?

the cakephp auth component hash password , try match password in db.
hashing password salt.
if sethash md5 then
md5($password.$salt) stored matched password in db.

so plz make sure storing password correct.

to enter dummy data. try debug $this->auth->password($password) copy result , insert in db.

if password wrong auth component reset password field internally.ie., why u result.

array (     [user] => array         (             [email] => myemail@gmail.com             [password] =>          )  ) 

this doesn't means password not available checking db.

happy baking
