It does:

# The standard Unix authentication modules, used with
# NIS (man nsswitch) as well as normal /etc/passwd and
# /etc/shadow entries.
@include common-auth
@include common-account
@include common-session

libpam-systemd is installed and common-session includes this line (and
it hasn't been modified in any way):

# and here are more per-package modules (the "Additional" block)
session required        pam_unix.so 
session optional        pam_systemd.so 
# end of pam-auth-update config

No, it does not work. This is Debian stable/Jessie with all the latest
updates installed. I have three identical machines setup like this and
on all three it does not work.

It looked to me like a problem in systemd/libpam-systemd. Do you still
believe I should file it against su (and runuser, and maybe sudo for
good measure)?
