[Bug 1454112] Re: Group permissions not respected with "--manage-gids" enabled

[Emile Snyder]

Also, I think this should be pointed out in the
https://help.ubuntu.com/community/SettingUpNFSHowTo#Group_Permissions
page (that page incorrectly, for the default Ubuntu config) states that
it's the group permissions on the client that matter, not the server.

But it's not a user editable page, and I couldn't figure out how/where
to submit a change in the time I had available to look.

Title:
  Group permissions not respected with "--manage-gids" enabled

Status in nfs-utils package in Ubuntu:
  Confirmed

Bug description:
  user at cloudVM:/mnt/extraFiles/chroot/home$ ls -l
  total 20
  drwxrws--- 6 storageUsers storageUsers 4096 maj 12 08:14 actualCommonFiles
  drwxr-xr-x 2 root         root         4096 maj 12 07:32 commonFilesR
  drwxrwxr-x 8 user  user  4096 maj 12 08:14 user
  drwxrwxr-x 2 user  user  4096 maj  9 16:52 guest
  drwxr-xr-x 3 storageUsers storageUsers 4096 maj 12 08:50 test

  user at cloudVM:/mnt/extraFiles/chroot/home$ groups
  user storageUsers commonFilesRW

       ---With "--manage-gids" enabled in /etc/default/nfs-kernel-server (default for Ubuntu 14.04):
  user at cloudVM:/mnt/extraFiles/chroot/home$ cd actualCommonFiles/
  bash: cd: actualCommonFiles/: Permission denied

       ---Without --manage-gids":
  user at cloudVM:/mnt/extraFiles/chroot/home$ cd actualCommonFiles/
  user at cloudVM:/mnt/extraFiles/chroot/home/actualCommonFiles$

  ========

  - Expected:

  "user" is member of "storageUsers" and should have Read, Write, and
  List rights for "actualCommonFiles". "cd" should be successful.

  - Happened:

  "user" was denied access to the "storageUsers" directory.
