Blob Blame History Raw
From 4caf0c14ad38a1dae494489b13f4109cdb3ba340 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Delay enabling services until end of installer

Service entries in cn=FQDN,cn=masters,cn=ipa,cn=etc are no longer
created as enabled. Instead they are flagged as configuredService. At
the very end of the installer, the service entries are switched from
configured to enabled service.

- SRV records are created at the very end of the installer.
- Dogtag installer only picks fully installed servers
- Certmonger ignores all configured but not yet enabled servers.

Fixes: https://pagure.io/freeipa/issue/7566
