Testing Ion Auth

[eluser]oniadvanced[/eluser]
Hi, Guys.

I've been testing Ion Auth which looks very simple however I'm trying to test the remember me option but I'm not sure how it should work. In the config file I'm setting some values like this:

$config['remember_users'] = true;
$config['user_expire'] = 10;
$config['user_extend_on_login'] = false;

So, I'm setting the 'user_expire' to 10 seconds but nothing happend after that time, It keeps logged in, It is supposed to kill the session and send me to the login area again, right? Someone knows what I'm doing wrong?

Thanks in advance.
