Subject: [PATCH] Apply patch to fix autorefresh with Kerberos

Patch from Eric Dorland

Closes: #470875

From: Wouter Verhelst
Subject: kerberos authentication works only the first time
Date: Fri, 14 Mar 2008 09:28:37 +0100

Package: offlineimap
Version: 5.99.8
Severity: normal

Hi,

I have the "autorefresh" configuration option specified in my
.offlineimaprc, and am now using the kerberos authentication.

However, this kerberos authentication seems to work only the first
time
offlineimap tries to fetch mails. The next time, it fails with this
output:

Thread 'Account sync Test' terminated with exception:
