From d5bbd817fe83aed1ee48ed4f478f3887c059f7b9 Mon Sep 17 00:00:00 2001 From: Andrew Bartlett Date: Wed, 24 Jan 2007 02:48:40 +0000 Subject: r20988: Call out to Heimdal's krb5.conf processing to configure many aspects of KDC behaviour. This should allow PKINIT to be turned on and managed with reasonable sanity. This also means that the krb5.conf in the same directory as the smb.conf will always have priority in Samba4, which I think will be useful.
