No question there. I was trying to say we do not need multiple 'auth-method' elements on web.xml But I think it should be possible to exclude a few URLs, like '/rest/foo' and '/rest/bar', so that they are completely unprotected in terms of Keycloak (e.g. via different security-constraint elements): https://github.com/aerogear/aerogear-unifiedpush-server/blob/2aabd073aaaa... In terms of "current logged in user on Angular.js": * For the "/rest/sender" and "/rest/device/registration" endpoints, I don't see a relationship to the user on Angular.js/AdminUI at all. Internally these 'unprotected' (or excluded) endpoints implement the HTTP_BASIC scheme themselves: * They treat the Application/Variant like a 'user', by performing a DB lookup of the give application/variantID * If that (Application or Variant) is found, the endpoints compare the given 'password' form the request w/ the "secret" on the Application or Variant But for these endpoints (sender and device-registration) there is no real user here like "Mr. Jay" or "Push-Admin Foo". The client (registration or sender SDK) performs the auth, by applying the ID and the secret: curl -3 -u "{PushApplicationID}:{MasterSecret}" .... https://server > > > > > I mean: I think there is no need to enable multiple <auth-method> args, > as > > we had the exclusion already working at some point, using their KEYCLOAK > > auth-method > > Stian did that inclusion which for me looks correct.
