Hi, We seem to have some progress, after reading this blog post about sssd performance tuning.
https://jhrozek.wordpress.com/2015/08/19/performance-tuning-sssd-for-large-ipa-ad-trust-deployments/ So now we see that on the FreeIPA server, everything is stable and always produces the results we expect with regard to users and group membership. It's also a bit speedier, which is nice. Unfortunately, on the clients, we are still seeing groups "disappearing" occasionally, We found this thread from late last year that seemed to state exactly what we are seeing, although our sssd_pac.log is empty. I have just added debug_level = 7 to [pac] in sssd.conf on server and client. https://www.redhat.com/archives/freeipa-users/2015-December/msg00180.html Did anything come of this?
