NuGet version (ArtsTech.AspnetCore.Authentication.Ntlm)


An AspnetCore middleware for NTLM auth on Posix


  • Samba and Winbind installed
  • Samba joined to AD
  • Winbindd service running
  • ntlm_auth accessible on PATH

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


Dotnet 6 Minimal API example

using ArtsTech.AspnetCore.Authentication.Ntlm;
var builder = WebApplication.CreateBuilder(args);   


var app = builder.Build();






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.
