How to set Integrated Windows Authentication in SignalR for some but not all hubs

Question

I need to use Windows Authentication for a hub, but since Im working in a bigger system, I can only access the SignalR Pipeline over the GlobalHost.

Ive tried using AuthorizedAttribute , but that does not set the Identity, since there is no Autorization Module registered.

Ive tried setting GlobalHost.HubPipeline.RequireAuthentication();

That set the Identity, but since it sets Authorization globally, other Hubs can not connect.

Finally, I tried adding a custom Authorization module, that should only apply to the one hub I want. But as soon as I make an exception for one Hub, the Identity isnt set again, and I get an UnAuthrorized response from the Authorized Hub.

Answer 1

I usually put the authentication attribute on top of my hub class.

 [Authorize(AuthenticationSchemes = JwtBearerDefaults.AuthenticationScheme)]
 public class myChat : Hub 
 {
 }

this is token-based authentication and you need to configure your send your authentication token from the client. https://learn.microsoft.com/en-us/as.net/core/signalr/authn-and-authz?view=as.netcore-3.1
