[keycloak-user] Accessing authenticated user's details

How about wrapping your application under a filter (or a valve in JBoss or Tomcat) ? From there you could populate your authenticated subject (or the session?) with whatever information your keycloak token could provide.
Would that be a good idea ?

Yes, JavaEE currently has no standard way of obtaining a user profile.

    So if I understand correctly the only way to handle multiple
    attributes of the user (e.g name and email) is to use the Keycloak
    IDToken approach and so be dependent on the Keycloak implementation
    (or create my own API that wraps this)?

      If you don't want Keycloak
        dependencies, you can use request.getRemoteUser() or
        request.getPrincipal().getName() to access just the userId of
        authenticated user. If you use "principal-attribute" in
        keycloak.json, it will return the configured attribute instead
        of userId, so you can receive for example username or email
        instead. But that way, you will be able to access just this
        single attribute.

          In the case of a web application (e.g. Tomcat app secured by
          the keycloak adapter) the web app might need to access details
          of the authenticated user (e.g. full name or email).

          I've found that this information is available from the session
          like this: 

          

          KeycloakSecurityContext session =
(KeycloakSecurityContext)request.getAttribute(KeycloakSecurityContext.class.getName());

            IDToken idToken = session.getIdToken();

            String email = idToken.getEmail();

          

          One issue with this is that all your web apps are tied to
          keycloak.

          

          Is this the right way to handle this?

          Are there alternatives?
