It appears that it first stops working in cups version 2.2.7 when there is a major change in cups/auth.c.
It is still broken in the current cups github repo master branch.
I have noticed it works correctly if you disable the unix domain socket, e.g. comment out
Listen /run/cups/cups.sock
in /etc/cups/cupsd.conf
