If this is not fixed, the attached config also breaks any cups package
updates as the package scripts get the authentication prompt and hang.

Actually it looks this is probably a bit different than the original
issue in this bug, sorry about that. However, I have attached our
cupsd.conf and any printers we are using have "OpPolicy authenticated".
With this config (the difference to stock Ubuntu config is AuthType
Default for /), for exam
@Esko, could you describe the setup enough so the description can be
used for a SRU (https://wiki.ubuntu.com/StableReleaseUpdates)?
Looking to the upstream commits and your diff, it looks like that one might be
the one fixing your issue

We had very similar symptoms (the user always gets a username/password
prompt when trying to print) but it seems for us PeerCred was not
working properly. I tried compiling the source tree from cosmic and it
worked correctly. I then took a diff between that and the bionic package
and the cups/auth.

To get kerberos authentication fixed again in CUPS would be extremely good!
I guess downgrading to SMB1 is not even an option in many bigger and/or more
open environments -- typically managed by someone else with security oriented
attitude.

Here is my proposed solution (attached) to the problem - I do not claim
to fully understand cups' authentication system but it seems to me from
looking at the old code to cups/auth.c and the new broken code that this
patch would make the unix domain socket authentication work the same as
it did bef
My suggested work around above does not fix the issue (completely)
because systemd is in charge of the socket - so as well as commenting
out "Listen /run/cups/cups.sock" in /etc/cups/cupsd.conf you have to
also do the following:
systemctl stop cups.service
systemctl stop cups.socket
rm /run/cups/c
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 /et
The above setup work fine in Ubuntu 17.10 as well which uses cups 2.2.4
