Active Directory Authentication on Node.js WebSocket

I've created a Node.js WebApp and placed it on Azure. This hosts a Socket.io WebSocket and Website that I want to protect behind a form of authentication. My initial plan was to use ActiveDirectory, but I can't find any information on connecting a WebSocket using that kind of authentication.

Is there a way to use Active Directory or another similar and easy to setup authentication to protect both the website and the WebSocket?

I am planning on connecting to this server-side web app from a local machine using a socket.io-client.
