This bug no longer exists in Ubuntu 19.04/disco.
Here is the log I get when I do ssh then "su -":
Apr 10 14:08:42 xeelee systemd[1]: Started User Manager for UID 0.
Apr 10 14:08:42 xeelee systemd[1]: Started Session 447 of user root.

user bonnaudl by root(uid=0)
Apr 10 14:09:08 xeelee su[28502]: pam_unix(su-l:session): session closed for
user bonnaudl
I still get this error:
$ systemctl --user status
Failed to connect to bus: No such file or directory
but this is for another bug report...

Bug description:
Hi,
here is how to reproduce this error:
1. log in to the root account with ssh
2. run "su - some_user_account"
Here is what I see in the logs:
Feb 28 15:21:45 xeelee su[9843]: Successful su for bonnaudl by root
Feb 28 15:21:45 xeelee su[9843]: + /dev/pts/10 root:bonnaudl

user bonnaudl by root(uid=0)
Feb 28 15:21:45 xeelee su[9843]: pam_systemd(su:session): Cannot create
session: Already running in a session
Feb 28 15:21:48 xeelee su[9843]: pam_unix(su:session): session closed for
user bonnaudl
In another usage scenario of "su -" there is no error message and the
creation of a new session:
