Error: uninitialized constant Authlogic

Hello,

I'm a Ruby / Rails beginner and tried to use the Authlogic plugin
which I have found here: http://www.binarylogic.com/2008/11/3/tutorial-authlogic-basic-setup

However I run into this error:

uninitialized constant Authlogic

Perhaps you can point me somewhere to fix that. As I said, it's all
new...

Sounds like you are using the Gem and not the plugin. You might have
forgot this:

# config/environment.rb
config.gem "authlogic"
