Rails role based authentication

Does http://code.google.com/p/rolerequi开发者_StackOverflow中文版rement/ Role requirement works with Rails 3? If not, where can I find a role based management plugin like this for Rails?

Thanks!

There's cancan.

Check out the railscast.

Try canard https://rubygems.org/gems/canard brings roles to the beautifully simple cancan.

Some people use Acl9 as well.
