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
