[Pkg-shadow-devel] Bug#1118274: passwd fails with domain\username format

[Sebastian DeJesus]

Package: passwd
Version: 1:4.17.4-2
Severity: important

Dear Maintainer,

The passwd command fails to work with domain user accounts specified in the "domain\username" format on Debian 13.
This is a regression from Debian 12 where passwd version 1:4.13+dfsg1-1+b1 handled this format correctly.

When attempting to change a domain user's password using the standard format, the command returns an error:
$ passwd domain\\username
passwd: Provided user name is not a valid name

This format previously worked in Debian 12 with passwd 1:4.13+dfsg1-1+b1 and should continue to be supported in
Debian 13 for users with domain/LDAP authentication (such as Active Directory).

This regression prevents domain users from changing their own passwords using their domain account credentials.
