User Authentication

[eluser]cahva[/eluser]
Well I have done it this way:
- Create the auth library It offcourse consists of login, logout, logged_in etc. methods
- add the auth library to autoload.
- Create the controller for the login and logout which has the login form etc.
- Now in every controller's construct you would have this:

Code:

function __construct()
{
    parent::Controller();
    if(!$this->auth->logged_in()) {
        redirect('login');
    }
    ...

I dont think 2 lines of code in every construct is asking too much
