Naturally I already did what the ShiroFilter does to get any Subject
checks going. However Subject.login() doesn't work because of the
reasons mentioned in my previous post (see the stacktrace - it enters
DefaultSecurityManager.createSubject where the context is (re-)created
and it won't have the request/response objects in it).
