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. Signed-off-by: Sachin Prabhu <sprabhu@redhat.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
