Comment # 48 on bug 1165351 from Luis Chamberlain

Note: I have a work around for now thanks to Anthony Iliopoulos, his suggestion
was to disable systemd from pam:

--- /etc/pam.d/common-session-pc.old    2020-03-25 13:42:38.404526416 +0100
+++ /etc/pam.d/common-session-pc    2020-03-25 13:42:47.308353223 +0100

 session    required    pam_limits.so    
 session    required    pam_unix.so    try_first_pass 
 session    optional    pam_umask.so

I'll also note that this issue is *still* present if you don't do the above,
but just disable NIS. I disabled NIS by commenting out /etc/yp.conf and
stopping ypserv.service and then disabling it. The only effective way to work
around this is disabling pam_Systemd.so from pam from commom-session-pc as
noted above.

But without a system to reproduce, we have no way of debugging it further. 

Thomas, I'll leave chivo with the pam_systemd.so enabled, but I'll disable it
on tuctuc. I'll keep using tuctuc for development, feel free to use chivo for
any further testing / debugging.
