Subject: kernel update to 6.8.2 broke idmapd group mapping
Date: Sat, 30 Mar 2024 12:56:39 +0100	[thread overview]
Message-ID: <CAAvCNcCDsAcZFoCuCgM_HrooSTjr5T9aQ2s_LC_81XUzVetwqw@mail.gmail.com> (raw)

Hello!

I have updated my Debian 11 with the Linux 6.8.2 kernel, running
rpc.nfsd with various NFSV4 clients.
Userland stayed exactly the same, so neither idmapd or nfs-utils were changed.

But I now see lots of weird group names (not usernames, they are
normal) from idmapd, but not all group name mappings are affected:
