Bug#1056166: systemd-homed: `passwd` fails

[Alexander Bochmann]

Package: systemd-homed
Version: 254.5-1~bpo12+2
Followup-For: Bug #1056166

Hello,

I can confirm this problem still exists in bookworm and 
bookworm-backports:

As soon as the Debian systemd-homed PAM configuration is activated 
by pam-auth-update, it's not possible to change passwords of 
users that come from /etc/passwd anymore.

This seems to be due to a PAM misconfiguration. I don't understand
enough of the Debian PAM setup to say why it doesn't work, but 
I tried replacing the rules with alternatives that I copied from 
an openSUSE Tumbleweed install, and using those it's possible to 
change details on users both from /etc/passwd and systemd-homed.

Alex.
