CodeIgniter Tank Auth Error

I can't seem to get tank auth installed correctly, I copied over the files, but everytime I visit 'localhost/auth' it gives me the error Unable to load the requested class: security.

The documentation I've been able to find is very light, and doesn't cover this error 开发者_JAVA技巧(or how to install it). I am installing on a windows box running WAMP. But am planning to move it to a linux box running apache after development.

Thoughts?

I had the same problem on latest codeigniter 2.1.0

Commenting the $this->load->library('security'); from auth.php controller will remove the error. Codeigniter 2.1.0 has security class automatically loading at the core.

I have updated my repo with the changes, hope someone finds it useful, https://bitbucket.org/mtsandeep/tank-auth-with-roles/overview
