Raw Blame History

From febfd9c64d748a435a9d0756d4710898a0e2aa49 Mon Sep 17 00:00:00 2001
From: Julien Rische <jrische@redhat.com>

Subject: [PATCH] ipa-kdb: Rework ipadb_reinit_mspac()
Modify ipadb_reinit_mspac() to allocate and initialize ipactx->mspac
only if all its attributes can be set. If not, ipactx->mspac is set to
NULL. This makes easier to determine if the KDC is able to generate PACs
or not.
Also ipadb_reinit_mspac() is now able to return a status message
explaining why initialization of the PAC generator failed. This message
is printed in KDC logs.
Fixes: https://pagure.io/freeipa/issue/9535
