Raw Blame History

From b623881ec039bffc758f53906f7e4f9b884f1cf4 Mon Sep 17 00:00:00 2001
From: Robbie Harwood <rharwood@redhat.com>
Date: Thu, 15 Mar 2018 14:37:28 -0400
Subject: [PATCH] Include preauth name in trace output if possible
Add a {patype} trace format specifier for a single pa-type value. Add
a krb5_preauthtype to string conversion function to trace machinery
and use it when formatting {patype} or {patypes}.
[ghudson@mit.edu: wrote conversion function; edited commit message]
ticket: 8653 (new)
(cherry picked from commit 9c68fe39b018666eabe033b639c1f35d03ba51c7)
