        # Allows you to scope everything to specific field(s). Works just like validates_uniqueness_of.
        # For example, let's say a user belongs to a company, and you want to scope everything to the
        # company:
        #
        #   acts_as_authentic do |c|
        #     c.validations_scope = :company_id
        #   end
        #
        # * <tt>Default:</tt> nil
        # * <tt>Accepts:</tt> Symbol or Array of symbols
