Arch Linux

Description: Samba 4.10.x breaks printing via cups

A useful description I found here: https://bbs.archlinux.org/viewtopic.php?id=245658
"It seems to be a problem in the integration of samba and kerberos:
Seens that it's necessary to build Samba with MIT Kerberos Support
From the release notes for the 4.10 release at https://www.samba.org/samba/history/samba-4.10.0.html, there is an interesting snippet included."

My setup are two computers:
A is Arch/win10 Dualboot
B is Arch/WinXP Dualboot
Printer is connected to B, B is acting as printer server.

As soon, as I update to Samba > 4.9.5, Printing von Computer A to B fails. It fails when B is running Arch and it fails if B is running Windows
printing works fine in any case with Samba <4.10 on A, if Win10 is booted, doesn't matter what OS is booted on B

When controlling the CUPS via the administrative Web Interface you can the the jobs pending and error messages like "NT_STATUS_LOGON_FAILURE"

As the Bug breaks working configurations and prevents using a basic feature like printing, I would expect the severity to be High

Additional info:
* package version(s) Samba, smbclient, libwbclient in versions 4.10.x(current) and 4.9.5
* config and/or log files etc.
* link to upstream bug report, if any

REMOVED FEATURES
================

MIT Kerberos build of the AD DC
-------------------------------

While not removed, the MIT Kerberos build of the Samba AD DC is still
considered experimental. Because Samba will not issue security
patches for this configuration, such builds now require the explicit
configure option: --with-experimental-mit-ad-dc

Steps to reproduce:
install, samba, cups, configure a printer to print via smb and see it fail...
