Yan, Not a fix for the behaviour of the different flows; but if you control the service application, you can set the tomcat ROOT web app to be the one you are trying to target.

Hello, We are running CAS 5.3.x on Tomcat9. One of our clients uses OIDC. Intermittently, after login, instead of getting into the app's landing page, they got redirected to the root context, which is the Tomcat page. What I noticed is at the end: 2021-01-20 23:31:49,158 DEBUG [org.pac4j.core.engine.DefaultCallbackLogic] - <redirectUrl: /> if redirectUrl says /, they got redirected to Tomcat page, which is incorrect. I turned off browser prefetch, that made no difference. Since this is intermittent, I compared with the good login. With successful login, what happens after OAuth20CasCallbackUrlResolver is: ProfileHelper, but with the ones being redirected to Tomcat, what happens after OAuth20CasCallbackUrlResolver is OAuth20AuthenticationServiceSelectionStrategy. Unfortunately, I do not know why the difference. Suggestions? The following are the logs of good login vs. incorrect login flow. I masked username as "username", as well as hostnames. Thanks!
