Raw Blame History

From 29855ec76bcb445543e1f2b16b13e5bcfeb67723 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Don't error in DogtagCertsConnectivityCheck with external CAs
The purpose of the check is to validate that communication
with the CA works. In the past we looked up serial number 1
for this check. The problem is that if the server was
installed with RSNv3 so had no predictable CA serial number.
It also was broken with externally-issued CA certificate which
cannot be looked up in IPA.
Instead use the IPA RA agent certificate which should definitely
have a serial number in the IPA CA if one is configured.
Fixes: https://github.com/freeipa/freeipa-healthcheck/issues/285
