UserAuth Mini-App Error

[eluser]Unknown[/eluser]
Hi everyone,

I just installed the UserAuth Mini-app Auth tool from the CI wiki. I followed the installation instruction, but when I go to login as the admin user, I get the following error:

"The requested URL /ci/user/login was not found on this server."

I installed CI in my Apache htdocs area.

Any feed back will be greatly appreciated.

Thanks in advance.
