CakePHP 2.1 Auth-> login () does not work, but adding a user

I searched a lot of posts in stackoverflow for an answer, and maybe I'm just missing something, but I can't get $ this-> Auth-> login () to work. I have tried many different sentences from other posts. I will try to be as careful as possible when describing other methods that I have tried.

I have a user add. MD5 hashing works correctly. I hashed the password and then verified it using the mid salad md5 http://www.miraclesalad.com/webtools/md5.php

I do not use hash salt. I use MD5 without salt.

I am using Postgresql 9.0 database. I know that some of CakePhp magicians do not work for all databases (or so they told me).

application /Config/core.php

Configure::write('Security.level', 'medium');

/**
* A random string used in security hashing methods.
*/

    Configure::write('Security.salt', '');

$this->Auth->fields = array('username' => 'user_name', 'password' => 'user_password');
