Alias "rights.RightsModule" is invalid in Yii rights extension - yii

Question

When I go to http://localhost/project/rights I get the below error:
Alias "rights.RightsModule" is invalid. Make sure it points to an existing PHP file and the file is readable.
I doubled checked my path. I already have user extension in modules folder and it works just fine. I've extracted rights in protected/modules/rights.
And this is my config/main.php file:
<?php
$sitedes = 'blah blah';
if($_SERVER['HTTP_HOST'] == 'localhost')
{
$dbhost = 'localhost';
$dbname = 'dbproject';
$dbuser = 'root';
$dbpass = '';
}
// uncomment the following to define a path alias
// Yii::setPathOfAlias('local','path/to/local-folder');
// This is the main Web application configuration. Any writable
// CWebApplication properties can be configured here.

It all seems OK, but it doesn't work. What to do now?

Answer 1

I noticed that permission for user folder is 755 and 700 for rights folder. It was a readonly folder. So I changed the permission to 755 and got another error about cannot find table. The below code was added to authManager section and now everything seems to work just fine.
'connectionID'=>'db',
