I seem to have an intermittent problem.
When I ssh into it my server,( using sssd and registered to a freeipa server). I often get
dates starting at 1970! I seem to be able to login without any issue.
I suspect this may be that our AD server has multiple realms. Strangely enough, our AD has
no "MYEDU.EDU" realm but has got an "AD.MYEDU.EDU", which is what I
see when it works normally.
I've logged the output of 'sssd -i -d 9 ' plenty of times, but I'm not
sure what to even start looking for, nothing obvious is noticeable at the moment.
I've noticed the same problem on Redhat 7, 8 and Ubuntu 18.04. Ubuntu 20.04 has not
shown this issue and just works. The dates from klist on Ubuntu 20.04 look OK.
They all have the same krb5.conf and sssd.conf.
How would I debug this?
What sort of things should I be looking at?
