From 723f7a1387f1d79541fdbe66ad3778f2aaa370c4 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Nguy=E1=BB=85n=20Th=C3=A1i=20Ng=E1=BB=8Dc=20Duy?= Date: Tue, 4 Oct 2011 08:55:09 +1100 Subject: [PATCH] daemon: return "access denied" if a service is not allowed MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The message is chosen to avoid leaking information, yet let users know that they are deliberately not allowed to use the service, not a fault in service configuration or the service itself.
