Description Carlos O'Donell 2019-08-30 16:10:47 UTC
Cleanup nsswitch.conf comments following upstream commits: commit 4b7c74179c8928d971d370e1137d202f891a4cf5 Author: Carlos O'Donell <firstname.lastname@example.org> Date: Wed Mar 20 12:40:18 2019 -0400 nss: Make nsswitch.conf more distribution friendly. commit d34d4c80226b3f5a1b51a8e5b005a52fba07d7ba Author: Carlos O'Donell <email@example.com> Date: Wed Mar 20 22:11:32 2019 -0400 nscd: Improve nscd.conf comments. This change adds a warning to nscd.conf about running multiple caching services together and that it may lead to unexpected behaviours. Also we add a note that enabling the 'shared' option will cause cache hit rates to be misreported (a side effect of the implementation).
Comment 5 Carlos O'Donell 2019-10-29 17:12:51 UTC
QA failure caught by gating is now fixed upstream. We need to backport this additional commit to RHEL 8.2, and Fedora 31/30 (Rawhide will catch up in the weekly sync). commit eed1f6fcdb0526498223ebfe95f91ef5dec2172a (HEAD -> master, origin/master, origin/HEAD) Author: Carlos O'Donell <firstname.lastname@example.org> Date: Tue Oct 29 11:58:03 2019 -0400 Comment out initgroups from example nsswitch.conf (Bug 25146) In commit 4b7c74179c8928d971d370e1137d202f891a4cf5 the nsswitch.conf file was harmonized with downstream distributions, but this change included adding "initgroups: files". We should not add initgroups by default, we can have it, but it should be commented out to allow it to inherit the settings for group. The problem is principally that downstream authconfig won't update initgroups and it will get out of sync with the setting for group.

Verified by reviewing /etc/nscd.conf config file.
