  # We have to configure Zero for Chef 11 mode in order to test users because:
  # 1. local mode overrides your `chef_server_url` to something like "http://localhost:PORT"
  # 2. single org mode maps requests like "https://localhost:PORT/users" so
  #   they're functionally equivalent to "https://localhost:PORT/organizations/DEFAULT/users"
  # 3. Users are global objects in Chef 12, and should be accessed at URLs like
  #   "https://localhost:PORT/users" (there is an org-specific users endpoint,
  #   but it's for listing users in an org, not for managing users).
  # 4. Therefore you can't hit the _real_ users endpoint in local mode when
  #   configured for Chef Server 12 mode.
  #
  # Because of this, we have to configure Zero for Chef 11 OSC mode in order to
  # test the users part of the data store with local mode.
