From 3f587569f2fdd9ec4db05748c5ed5ebbfc1ab5c9 Mon Sep 17 00:00:00 2001 From: Simo Sorce Date: Mon, 14 Oct 2013 16:41:13 -0400 Subject: Add option to specify allowed usage. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Credentials can often be used both to accept and to initiate contexts. With this option admins can allow a specific usage only. This is to avoid allowing an unprivileged process to fool a remote client by allowing it to impersonate a server, when we only want to allow this service to use credentials to initiate contexts.
