Bug#880549: nfs-kernel-server: NFSv4 sec=krb5p option broken on stretch

[Dietrich Clauss <dietrich@clauss-it.com>]

Package: nfs-kernel-server
Followup-For: Bug #880549

This bug is still present in Buster.

It can be workarounded by using the mount option "vers=4.0".

NFS versions 4.2 (default in Buster), and 4.1 are affected by this bug.
Version 4.0 works fine.  Can anyone confirm this?
