From 419e92b1499c77ddf3648d6b99ed482a57b3e713 Mon Sep 17 00:00:00 2001
From: Andreas Schneider <asn@samba.org>
Date: Wed, 30 Nov 2011 17:39:22 +0100
Subject: [PATCH] s3-net: Don't use an internal krb5 for kdc lookup.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This replaces the use of the internal krb5_locate_kdc() function with
our own get_kdc_list() function.
