Details

I upgraded the cups package to the last version. Printing looks good in the first seconds and it seems as if the dox are sent over the network. Then a dialog window pops up reading "Authentication required for printing document "..."." The dialog contains a field "negotiate" and a checkbox "Remember password". It doesn't matter what I enter into the "negotiate" text box, none seems right, neither the local user's or root's passwd, nor the passwd of the account creds' passwd I'm supplied with. The only option that makes the dialog vanish is Cancel. A look into the printer queue then shows an entry reading "Tree connect failed (NT_STATUS_ACCESS_DENIED)".

A look into /etc/cups/printer.conf tells me that "AuthInfoRequired none" has changed to "AuthInfoRequired negotiate". When I stop cups and the change that entry back to "none", start cups, the same happens again: The dialog pops up and the entry in /etc/cups/printers.conf has been overwritten and reads "AuthInfoRequired negotiate" again.

Steps to reproduce:

-Add samba printer that requires authentication.
-Print a document

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.

Please test by building the packages in the following order
talloc with extra-x86_64-build
tdb with extra-x86_64-build
tevent with extra-x86_64-build -- -I ../talloc/talloc-2.1.16-1-x86_64.pkg.tar.xz
ldb with extra-x86_64-build -- -I ../tdb/tdb-1.3.18-2-x86_64.pkg.tar.xz -I ../talloc/talloc-2.1.16-1-x86_64.pkg.tar.xz -I ../tevent/tevent-1\:0.9.39-2-x86_64.pkg.tar.xz
samba-git with extra-x86_64-build -- -I ../tdb/tdb-1.3.18-2-x86_64.pkg.tar.xz -I ../talloc/talloc-2.1.16-1-x86_64.pkg.tar.xz -I ../tevent/tevent-1\:0.9.39-2-x86_64.pkg.tar.xz -I ../ldb/ldb-1\:1.4.6-1-x86_64.pkg.tar.xz
This is the last commit that can be built with ldb 1.4.6 before switching to ldb 1.5.4

Why this issue is still "unconfirmed", as many people report the same problem, and why the priority is still low? I currently need to block samba and the associated packages in pacman, as any update to > 4.9.5 is breaking my system.? And as far as I understand a changed build setting would resolve the issue!
