"authentication" is an empty array - everything enabled

[CaptainN]

As far as I can tell I've installed and set everything up correctly (the oauth1 end points even work correctly), but I don't see anything information about the service in /wp-json. It's just an empty array:

"authentication": [],

Is this a bug, or did I set something up incorrectly?

Since I'm here, I'm working with a package that expects 4 end points, and the docs only mention 3. How should I structure an 'authenticate' end point? I found one implementation that uses '/?json_route=/' but that just delivers me to a json blog (with the above empty authentication array).
