Shows off a few samples for acts_as_authentic configuration

authlogic_config_example.rb

class User < ActiveRecord::Base
  # gradual engagement is needed, to allow admin creation of users
  # users should create authorization data only when they need to
  # access some system feature that requires authentication
  # So ... our gradual engagement scheme for authlogic:
  # 1. admin creates user, setting only name and phone number (required)
  # admin may set email address (optional)
  # 2. user is sent email invitation with link to activate their account
  # admin can re-send email at user's request
  # 3. user sets login and password/password_confirmation using activation form
  # #active attribute set true in controller #create method
  # note: cannot use :if condition since authlogic uses them
  # fatal flaw: will break any authlogic :unless condition
  # fortunately, authlogic currently does not use the :unless condition

    ### authlogic minimum defaults to 4, our system is not as critical :)
