Some setup you must do manually if you haven't yet:

1. Ensure you have defined your external database URI, in 
config/initializers/user_mgmt.rb.
       For example:
     config.external_database_URI = "http://localhost:3000/"
2. Ensure you have defined root_url to *something* in your config/routes.rb.
   For example:
     root :to => "home#index"
3. Ensure you have flash messages in app/views/layouts/application.html.haml.
   For example:
        %body
          #main
            - if flash[:notice]
              #notice.message= flash[:notice]
            - elsif flash[:warning]
              #warning.message= flash[:warning]
