Hi
Great article. Just what I was looking for.
One thing I’m not clear on is how to make a subsequent request to the authorisation server. I need to do something similar to the code in your article in the OnCreatingTicket method i.e. make a call for more info from the authorisation server (not the user info call) and do it from a MVC controller action in my app. I need to send an authorization header with a bearer token containing the access token. In the OnCreatingTicket, you get the access token from the context, but I don’t know how to get the access token from within a controller method.
Regards Richard.

when setting up the 2nd app (.net core) i get the following error.

There isn’t that much to change to set it up, anyone know what i did wrong?

An unhandled exception occurred while processing the request.
SocketException: No such host is known
System.Net.Http.ConnectHelper.ConnectAsync(string host, int port, CancellationToken cancellationToken)

HttpRequestException: No such host is known
System.Net.Http.ConnectHelper.ConnectAsync(string host, int port, CancellationToken cancellationToken)

FYI the URL appsetting had “Desktop” appended to the end for some reason, copy and paste error i guess

In the controller, Aren’t you able to access the request?
The token is stored in request.Headers.Authorization .
This is one way of getting the token but there are so many other ways. No need for subsequent requests to the authentication server.

I want to setup an SSO login page for an existing identity server. I want it setup like this but at the end, I want it to 302 to another app with the auth token. Is this facility built in?
