Hi,
I was playing around with the examples, more specifically with the
customer-portal-js which is accessing the database resource. In that
CustomerService I was trying to get access to the Principal and trying to
extend to return in addition the username of the logged-in user:
@Path("customers")
public class CustomerService {
@Inject
Principal principal;
//@Context
//SecurityContext sc;
//Principal principal = sc.getUserPrincipal();
//@Context
//ContainerRequestContext request;
//SecurityContext sc = request.getSecurityContext();
//Principal principal = sc.getUserPrincipal();
@GET
@Produces("application/json")
@NoCache
public List<String> getCustomers() {
ArrayList<String> rtn = new ArrayList<String>();
rtn.add("Bill Burke");
rtn.add("Stian Thorgersen");
rtn.add("Stan Silvert");
rtn.add("Gabriel Cardoso");
rtn.add("Viliam Rockai");
rtn.add("Marek Posolda");
rtn.add("Boleslaw Dawidowicz");
rtn.add(principal.getName()); //<--- add username to the list
return rtn;
}
}
But this throws a npe as the principal is always null. I noticed that the
JaxrsBearerTokenFilter is adding to the ContainerRequestContext a new
SecurityContex, of which the getUserPrincipal method returns the
KeycloakPrincipal. But I can't figure out how to get access to this from
the CustomerService.
My intention is to verify if the logged-in user is accessing his own
resources, and e.g. is not trying to update data of somebody else. E.g. the
id should match principal.getName() in following:
@POST
@Path("/users/{id}/friends")
public void addFriend(@PathParam("id") String userId, Friend friend) {
...
}
Any suggestions? It would be nice if, beside the KeycloakPrincipal is
injectable, to be able to define something like @IsOwner:
public void addFriend(@PathParam("id") @IsOwner String userId, Friend
friend)
or even more concise:
public void addFriend(@IsOwner("id") String userId, Friend friend)
Kind regards,
Dirk Franssen

What I like about the current admin console approach is that there is no
book keeping required by the browser. The Angular app has really no
knowledge of how it is being secured as its all driven by the server.
Also, you need to remember that the admin console was designed to be run
in a non-Java EE, non-servlet environment. While this is a requirement
for Keycloak, it may not be for your application. So, what I'm saying
is that for your angular application, you could rely on the servlet
container and keycloak adapter to maintain a session cookie and identity.
What I like about the keycloak.js approach is that there is no
server-side adapter required for the UI. The UI could be hosted off any
number of static web sites and use CORS invocations to any number of
Restful services.
There's also the debate of public vs. confidential clients. The
keycloak.js approach requires a public client. My understanding was
that confidential clients exist so that only an authenticated client
(client *NOT* user) is able to obtain an access token. I'm not exactly
sure what additional security benefits are obtained here beyond this.
I've been trying to ask this very question on OAuth mail lists but have
been unable to get a response so far.

Personally, I think that in most cases for a client-side web app the best
approach is to let the client-side do the oauth flow (the approach we're
currently taking in keycloak.js). It does depend on your application
though, and if you're application has a strict one html5 app calls one REST
service then http-only cookies are an option. I don't see any real benefits
of it though, and I believe it significantly complicates things.
Have a look at
http://blog.auth0.com/2014/01/07/angularjs-authentication-with-cookies-vs...,
I think it provides a good summary of the pros of the token approach.

Hi Stian and Bill,
thanks for your replies! I'll check out the blog post and try the approach
with a web.xml and a keycloak.json in the backend for now. I'll keep you
posted on what I end up with on the client side.
Cheers,
Nils

One of the problems with the keycloak.js approach is that we have no way
to perform a single log out or to force a logout of a specific user. I
think the OpenID Connect spec may have a way with IFrames to do this
sort of thing though. I didn't really get it at first glance though.
