[quote author="Gromozeka" date="1240697657"]I tried to google any info about this case, but found nothing.

It seems to me that the problem is in PostgreSQL driver for CodeIgniter, in session management. Unfortunately I can't prove it -- there is no PostgreSQL on my hoster's server.
Would you test how sessions work on PostgreSQL in your aplication regardless of Tank Auth? Does any similar error occur?[/quote]

I think is very dificult to port to postgresql, because postgresql is realy different with mysql for exemple no unix time function in postgresql.

For testing i have install mysql to see the demo of tank auth.
I can create a account.
I recive de mail for validation.
I can validate de account.
I can login without capcha.
I can logout
I can login with capcha

include thank auth to my aplication?
I try like this, tell my if it is correct?

Code:

class Welcome extends Controller {

    function Welcome()
    {
        parent::Controller();    
        $this->load->config('tank_auth', TRUE);
        $this->load->helper(array('form', 'url'));
        $this->load->library('form_validation');
        $this->load->library('tank_auth');
        $this->lang->load('tank_auth');
    }
    
    function index()
    {  
        if ($this->tank_auth->is_logged_in())  
        {
            $this->load->view('welcome_message');
        }  
         else  
        {  
             redirect('/auth/login/');
        }  
    }
}

It is possible to manage users role with tank auth ???
If it is not possible, can you tell my the way to extend the thank auth with role and or profile for users?
