Authlogin by default is supposed to auto login when the user's persistence token changes. It seems to fail in my Rails app. I set up the following single table inheritance user model hierarchy:

class BaseUser < ActiveRecord::Base
end

class User < BaseUser
  acts_as_authentic
end

  create_table "base_users", :force => true do |t|
    t.string   "email"
    t.string   "crypted_password"
    t.string   "persistence_token"
    t.string   "first_name"
    t.string   "last_name"
    t.datetime "created_at"
    t.datetime "updated_at"
    t.string   "type"
  end

To get auto login to work, I need to explicitly log users in in my UsersController:

  def create
    @user = User.new(params[:user])
    if @user.save
      UserSession.create(@user) # EXPLICITLY LOG USER IN BY CREATING SESSION
      flash[:notice] = "Welcome to Askapade!"
      redirect_to_target_or_default root_url
    else
      render :action => :new
    end
  end

I was wondering if it's anything to do with STI, or that the table is named "base_users" and not "users". I set it up before without STI and it worked so I'm wondering why once I put in place this hierarchy, it fails. Thanks!
