Ubuntu 18 Desktop, NIS, GUI

I was annoyed when a newly installed machine running Ubuntu 18.04 Desktop crashed when connecting to user accounts served remotely via NIS. Ubuntu v16 worked fine. What was wrong? After many blind alleys I found these steps online somewhere and this solved the problem for me.

$ sudo cp /lib/systemd/system/systemd-logind.service /etc/systemd/system/
$ sudo vim /etc/systemd/system/systemd-logind.service
$ diff /lib/systemd/system/systemd-logind.service /etc/systemd/system/systemd-logind.service
< IPAddressDeny=any
> IPAddressDeny=
$ sudo systemctl daemon-reload
$ sudo systemctl restart systemd-logind.service

I was encountering the following error message in /var/log/syslog.

systemd-logind[782]: do_ypcall: clnt_call: RPC: Unable to send; errno = Operation not permitted

The solution (that worked for me) was found among replies to a bug report, after I dug through things for a while.

I post this here in the hope that it will help someone else in the same situation.
