 This devise plugin has not been tested with DatabaseAuthenticatable enabled at the same time. This is meant as a drop in replacement for DatabaseAuthenticatable allowing for a semi single sign on approach.
 
 The field that is used for logins is the first key that's configured in the `config/devise.rb` file under `config.authentication_keys`, which by default is email. For help changing this, please see the [Railscast](http://railscasts.com/episodes/210-customizing-devise) that goes through how to customize Devise.
