If I handled the SSO oauth as client in the backend [ASP.NET] how to integrate it with the frontend?
I'm not familiar with OpenIdConnect/OAuth and I had to integrate my project with my organization's SSO
In the backend (ASP.NET) I did it and handled the callback and everything and made it as an OAuth client and it is that what gets the access token and everything
now the frontend (Angular) is another service with another domain how to make the angular app to read the authentication if the user is authenticated or his authentication is expired or not and what's his role and claims and so on and the right way to do it
so I don't want to generate now client id and client secret for the Angular App service but I want it the same as the backend one and to be integrated together and once it done from the backend should be passed to the frontend in short how to pass the authentication from the backend (which is just a client) to the frontend app so I don't want to generate now client id and client secret for the Angular App service but I want it the same as the backend one and to be integrated together and once it done from the backend should be passed to the frontend I need the backend to handle the SSO authentication integration like getting the token and user info and registering it in the database if a first time or some actions and just passing it to the frontend but I need the right way to do, like if the SSO token is expired or something the Angular App must be aligned up with that also what is that cookie called

that I see after the sso login and how it works the asp.net app still shows me that the request is not authenticated even within it
it comes here to this selected commented code after the sso is logged successfully so it is supposed to be work18 Replies

There are multiple conceptual ways to solve it. Most important question - Is this backend a general purpose one, or is it dedicated to this specific frontend app? Also does it have to be on a different domain?

yea I implemented normal jwt auth before
the oauth is a new thing for me
+1 to what TeBe mentioned, I'd have pointed you in the BFF direction as well. The alternatives for cross-domain cookies are usually JWTs as request headers but that comes with an entire new box of problems to discover
If you can avoid it, try to find a working setup which allows you to use cookies (E.g. if the apps are on the same subdomain)
