Public bug reported:
Binary package hint: nfs-kernel-server
When using Lucid as the NFS server, changing group ownership of a
file/directory fails for the user even if he/she is member of the target
group. I have tested this with Lucid and Maverick servers with nfs-
kernel-server installed, and it works correctly on Maverick, but not on
Lucid. I have tested with clients on RedHat, Ubuntu (Lucid and Maverick)
and Solaris 10, and the problem is isolated to Lucid. I have tried to
upgrade to 10.04.2, but the problem persists.
Please see below for testing output
