Bug#1012097: NIS broken in sid
Package: libnssswitch-nis
Version: 3.1-4
Severity: grave
It seems that currently unstable has a totally not working NIS binding for
users. I
performed my trials using an existing setup (bullseye-based NIS master+slaves
and
clients network in the real life).
I recently upgraded a bullseye NIS client box to sid for testing and discovered
that while
ypbind-mt is regularly working, the usual mapping of NIS users has gone.
To be sure of the issue I prepared a vagrant bullseye VM and bound that to
the regular bullseye NIS master as usual: perfectly working.
Then I full-upgraded to sid with the same broken result:
vagrant@debian:/etc$ ypcat passwd

{sorry, I stripped the full output for privacy)
vagrant@debian:/etc$ id lovergine
id: ‘lovergine’: no such user
vagrant@debian:/etc$ cat /etc/nsswitch.conf

# If you have the `glibc-doc-reference' and `info' packages installed, try:
# `info libc "Name Service Switch"' for information about this file.

My next step will be running a full-sid setup for a test network, but I don't
see any reason why the working NIS maps could be broken, my guess is that
the problem is connected to some inner libnss/libc issue.

This was actually a bug in libc6, which affected the compat module,
while explicitly using the nis module worked. This has been introduced
in glibc 2.33 and fixed in glibc 2.34 that just landed in sid.
Merging this bug with the existing one on the libc6 side.

Aurelien
