Hi folks,
I read somewhere that it is not recommended to run nscd to cache
passwd on ipa clients, but I wonder: What if?
I still have the problem that sometimes some sssd components
disappear somehow, e.g. sssd_pam. The logfile on our mail gateway
said
:

Some EMails were bounced with user unknown at the same time, so I would
guess there is a coincidence. Question is, could nscd be an option here,
providing an additional cache for user accounts? What side effects could
come up?
Platform is Debian 9, sssd is version 1.16.2, nscd version 2.24.
Every helpful comment is highly appreciated.
Regards
Harri
