[keycloak-user] How touser Servlet OAuth Client

[Marek Posolda]

You're not wrong. With ServletOAuthClient you have control when you 
redirect user to the KC login screen. But you're completely independent 
on Wildfly container security layers, hence no propagation to EJB layer.

If ServletOAuthClient is good for you, depends on the usecase you want 
to achieve. Maybe it is better for you to add some security-constraints 
URL to your web.xml  (for example "/my-protected-url") and you will 
redirect your application to /my-protected-url (with 
httpResponse.sendRedirect) whenever you want your application to be 
logged with keycloak. Then once KC authentication is finished and your 
application will visit "/my-protected-url" as authenticated user, you 
will redirect back to the original URL before authentication.

Not sure if EJB propagation will happen once you're authenticated, but 
visit unprotected URL though... But at least you can give it a shot.
