From 921b13a1c454aabc5dec6e7f33f7ae3ffa80febf Mon Sep 17 00:00:00 2001
From: Sumit Bose <sbose@redhat.com>

Subject: Read KDC info from file instead from environment

Then name or IP adress of the KDC is written into the pubconf directory
into a file named kdcinfo.REALM. The locator plugin will then read this
file and pass the data to the kerberos libraries.
