# For more information on Warden strategies, read this: https://github.com/hassox/warden/wiki/Strategies
class SuperCoolWardenStrategy
  def valid?
    # you have access to env and request
    # return true/false if this is strategy should run or not
    # if it returns false, it will move onto the next strategy in the list
    # defaults to true if you don't write this method
  end

  def authenticate!
    # again, this has access to env and request
    # write your authentication logic
    # call `success!(user)` to set the user object
    # call `fail!` to fail login explicitly
    # to move on to the next strategy, you can explicitly call `pass` or just do nothing
  end
