Bug#682709: nfs-kernel-server: NFS4 krb5 mounts hang under nfs-utils 1.2.6-3

[Heiner Markert <mephisto@gmx.net>]

Package: nfs-common
Followup-For: Bug #682709

Hello everybody,

I am affected by this bug after doing a test installation of wheezy: kerberized nfs4 mounts stop working.
The patched .deb-files from Daniel Hess (post #44) work for me and solve the issue.
Please consier including this patch into the debian packages in order to fix the regression with kerberized nfs.

Best regards
Heiner
