Needed to extend Devise to integrate and authenticate with a legacy app. Stitched this solution together after reading multiple articles and trying various combinations therein.
# config/initializers/devise.rb
require 'devise/models/remote_authenticatable'
require 'remote_auth_strategy'
Devise.setup do |config|
# all the other shenanigans...
config.warden do |manager|
manager.intercept_401 = false
manager.default_strategies(:scope => :user).unshift :remote
