  # In a before filter or helper
  # or other middleware:
  @current_user = User.find_by_login(webauth.login)

  # or whatever...

  # config/application.rb:
    require 'rack-webauth'
    config.middleware.use(Rack::Webauth)

  # ApplicationController:
    include(Rack::Webauth::Helpers)
    # optionally:
    delegate :logged_in?, :to => :webauth

If you want to make your site publicly available, but still enable WebAuth and have that information in your Rails application, you need a patch to WebAuth. It is available from here. Also see the corresponding thread for more information.
