From e49a29bd0eacce9d4956c4daf777a330115b369d Mon Sep 17 00:00:00 2001 From: Sachin Prabhu Date: Fri, 16 Mar 2012 19:25:52 +0000 Subject: [PATCH] Try using machine credentials for RENEW calls Using user credentials for RENEW calls will fail when the user credentials have expired. To avoid this, try using the machine credentials when making RENEW calls. If no machine credentials have been set, fall back to using user credentials as before.
