EntraID + F5 as Oauth client/resource server not sending ID Token to app

And as said F5 is fine validating the token
Now if you want your backend web application cluster to be able to validate oauth tokens, you need to configure it as resource server too

But you should think is there really such need?
Why not just leave F5 do the the job and inject a HTTP header which web app can consume.

I am still wonder how access token reach web app. Have you configure oauth bearer sso on F5?
