Thanks for everyone's help! I think I understand now: the key is if we want to
use guix, then we really do want to run NSCD and SSSD on these RHEL/CentOS
systems if at all possible.
So I think we just now need to follow the instructions here?
https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/system-level_authentication_guide/usingnscd-sssd
Or do you recommend a different way to run NSCD and SSSD at the same time on
RHEL/CentOS systems?
Once we figure this out maybe we should add a note about this in the Guix docs
here:
https://guix.gnu.org/manual/en/html_node/Application-Setup.html
Especially if Fedora is intending to remove NSCD?
Thanks!
Chris
