From 7c868c3dbc0df55ffdd84846462e869d5e630f7f Mon Sep 17 00:00:00 2001
From: Rob Crittenden <rcritten@redhat.com>
Date: Mar 15 2012 08:55:12 +0000
Subject: Add subject key identifier to the dogtag server cert profile.


This will add it on upgrades too and any new certs issued will have
a subject key identifier set.

If the user has customized the profile themselves then this won't be
applied.
