ArtsTech.AspnetCore.Authentication.Ntlm 1.0.2

ArtsTech.AspnetCore.Authentication.Ntlm

An AspnetCore middleware for NTLM auth on Posix

Requirements

• Samba and Winbind installed
• Samba joined to AD
• Winbindd service running

Configuration of Samba/Winbind is out of scope of this readme (and its quite beyond me).

Usage

Dotnet 6 Minimal API example

using ArtsTech.AspnetCore.Authentication.Ntlm;
var builder = WebApplication.CreateBuilder(args);   
builder.Services
     .AddRazorPages()
     .AddAuthentication(NtlmDefaults.AuthenticationScheme)
     .AddNtlm();

builder.Services.AddAuthorization();

var app = builder.Build();
app.UseStaticFiles();

app.UseRouting();

app.UseAuthentication();
app.UseAuthorization();

app.MapRazorPages();

app.Run();

FAQ

Why doesn't this support role-based access control (RBAC)?

Sorry, I aim to do one thing with this project, and that is to implement NTLM auth on Linux. You add a custom Claims Transform to add the Role claims from an LDAP query. Just register your IClaimsTransformation in your service provider.
