Testing And Unstable • [Testing - Trixie] Can't unlock screen with i3lock

Hi,

I'm using Debian testing, since one week ago (more or less) i3lock stopped unlocking (after an update).

I'm using NIS to authenticate the user. The user can login without problems, it can also su to root.

In /var/log/auth.log I'm getting when I try to unlock:

unix_chkpwd[8434]: check pass; user unknownunix_chkpwd[8435]: check pass; user unknownunix_chkpwd[8435]: password check failed for user (helder)i3lock: pam_unix(i3lock:auth): authentication failure; logname=helder uid=1000 euid=1000 tty=:0 ruser= rhost=  user=helder

Searching for a solution found that the problem might be on the unix_chkpwd permissions, but I think those are correct:

$ ll /usr/sbin/unix_chkpwd.rwxr-sr-x 43k root shadow  8 Apr 23:35 /usr/sbin/unix_chkpwd

Tried also running i3lock using "--debug" but found no relevant information.

From the dpkg log the following pam related packages were upgraded:

2024-05-07 10:16:56 upgrade libpam-systemd:amd64 255.4-1 255.5-12024-05-07 10:17:00 upgrade libpam0g:amd64 1.5.2-9.1+b1 1.5.3-72024-05-07 10:17:00 upgrade libpam0g:i386 1.5.2-9.1+b1 1.5.3-72024-05-07 10:17:00 upgrade libpam-modules-bin:amd64 1.5.2-9.1+b1 1.5.3-72024-05-07 10:17:05 upgrade libpam-modules:amd64 1.5.2-9.1+b1 1.5.3-72024-05-07 10:17:05 upgrade libpam-modules:i386 1.5.2-9.1+b1 1.5.3-72024-05-07 10:17:06 upgrade libpam-runtime:all 1.5.2-9.1 1.5.3-7

I don't know if the problem resides in one or more of these packages.

How can I debug this problem?
