sssd version 1.15.0 running on Ubuntu Xenial.
In my setup sssd is not automatically refreshing computer account tickets after 30 days,
for some reason.
I found te msktutil package, which has a cron job which runs msktutil --auto-update each
day.
So far so good.
However msktutil --auto-update fails but msktutil --update works OK.
Can anyone drop me a hint please why this might be so?
Snippets from the verbose output below.
