Getting WindowsIdentity in a linux-based node.js express-app

I have an express.js intra-net app running on linux, serving windows-domain users inside the company.

I need to get in server-code the name of the logged-in user on the machine where the browser-request has originated from.

On ASP.NET I write:

System.Security.Principal.WindowsIdentity.GetCurrent().Name

Is there any such node.js equivalent?
