It has to be configured at the Context level if it implement Authenticator.
The same is true for your code above, since the Context isn't known until
then. For what you want, you could probably also use a non-Authenticator
valve, and call request.setUserPrincipal with the Principal that is returned
by the Realm. Then BasicAuthenticator will think that you are already
authenticated, and let you through.
