This issue is open for serval month in service as well.
Enviroment: Windows AD network
SLES: sssd start fine and work fine
SLED: sssd doesn't start.
I had reinstalled the laptop several times- same result.
Now I installed a new version on a USB stik - same result.
it seem when installing workstation extension is the problem. When installing we, it changes the kernel as well.

I appreciate if my sssd get started again since it makes work in LAN easier.
