User authentication with CodeIgniter

Question

I am writing a web application using PHP. I want to use the MVC pattern for this, and decided to go with CodeIgniter. My application will have some pages which will require auth

Answer 1

I was looking into the same thing recently, and I found a CodeIgniter fork called Kohana that includes a nice authentication module. If you are set on CI, maybe adapting Kohana's auth module backwards to CI would save you some time? If you have just started out on your project and PHP5 is OK to use, consider switching over; they are very similar frameworks.
