ASP.NET Core Windows Authentication on Linux

Question

I run ASP.NET Core web application in a Linux container. I need to provide Windows authentication for my application. How can this be implemented?

I assume that the problem can be solved using a reverse proxy server that can authenticate via Kerberos.

Answer 1

Starting with ASP.NET Core 3.0, it is now possible to use Windows Authentication on Linux and MacOS by adding the Microsoft.AspNetCore.Authentication.Negotiate NuGet package, and using this in your Startup.ConfigureServices method:

services.AddAuthentication(NegotiateDefaults.AuthenticationScheme)
   .AddNegotiate();

And this in Startup.Configure:

app.UseAuthentication();

And some additional configuration that's described in the documentation.
