Who and w not nss aware?

[John Hearns]

It seems bizarre, but the who and w utilities say there are no users on my
system.
My account  is an Active Direcotry account and sssd is running.

johe@ibis:~$ who

johe@ibis:~$ w
 10:09:26 up 16:47,  0 users,  load average: 0.60, 0.59, 0.48
USER     TTY      FROM             LOGIN@   IDLE   JCPU   PCPU WHAT

I guess this is known behaviour?

I would suggest to run the commands with strace to see what the
command tries to do. Iirc the user name is actually read from the utmp
file and SSSD is not called at all here. So the issue might already
happen earlier that the needed entry isn't written to utmp.

HTH

bye,

Thanks Sumit.  Rather bizzarely my workstation has no /var/run/utmp file.
I rebooted yesterday - you would think a file like that would be created at
boot time if it did not exist. Weird!

AAARGGGGHHH In the Nae of the Wee Man what posessed Poettering to place a
strange file name in /lib/systemd/system which stops you grepping in that
rather vital directory...

Looks like the utmp file should be created by the service
systemd-update-utmp.service
Iwill investigate on my system, clearly this is not one for this list, sorry

Ending this one.  On an Ubuntu system /var/run is a link to /run . That
link was missing on my  system.
But WHYYYY  var things go into /var Not the root partition FFS.
' speaking as someone who builds HPC clusters. You might just have an NFS
mounted root partition, which is identical for thousands of compute nodes.
You might liek to have yiur /var as a local tmpfs in RAM, on a local
storage device, or as a uniqeuly named writeable NFS share on the
provisioning node.
Why in the heck assume that VARiable things should go elsewhere than VAR
