[Bug 976632] Re: nfs4 mounts are not mapping userids, uses nobody/nogroup

[Hamilton Turner]

Just experienced this issue. Used TJ's fix with success, but I had to
also restart nfs on the server - multiple restarts of idmapd did
nothing. I did not try restarting the client.

FWIW, here's my details. Primary difference is that my server is a
CentOS box.

Client: 
       Linux 3 3.11.0-23-generic #40~precise1-Ubuntu SMP Wed Jun 4 22:06:36 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
       nfs-common 1:1.2.5-3ubuntu3.1 
       nfs4-acl-tools: 0.3.3-1
       nfswatch: 4.99.11-1

Server: 
       Linux <snip> 2.6.32-431.5.1.el6.x86_64 #1 SMP Wed Feb 12 00:41:43 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
       nfs-utils-1.2.3-39.el6.x86_64
       nfs-utils-lib-1.1.5-6.el6.x86_64
       nfs4-acl-tools-0.3.3-6.el6.x86_64

Title:
  nfs4 mounts are not mapping userids, uses nobody/nogroup

Status in “nfs-utils” package in Ubuntu:
  Confirmed

Bug description:
  I have:
  machine A - NFS4 server, Ubuntu 11.10
  machine B - NFS4 client, Ubuntu 11.10
  machine C - NFS4 client, Ubuntu 12.04 (development)

  All machines have the same userids and group ids.

  Machine 4 exports are the following:

  /export/dir1  10.0.0.0/24(rw,nohide,insecure,no_subtree_check,async)
  /export/dir2 10.0.0.0/24(rw,nohide,insecure,no_subtree_check,async)
  /export/dir3        10.0.0.0/24(rw,nohide,insecure,no_subtree_check,async)

  On both Machine B and C, the mounts are defined in fstab as:

  10.0.0.1:/dir1        /mnt/mydir      nfs4    _netdev,soft,retry=2,auto    0       0
  10.0.0.1:/dir2       /mnt/mydir2     nfs4    _netdev,soft,retry=2,auto    0       0
  10.0.0.1:/dir3      /mnt/startrek   nfs4    _netdev,soft,retry=2,auto    0       0

  These NFS shares have been configured for about 6 months, no change to
  the configuration.

  However, on the newly upgraded machine C, when the NFS4 filesystems
  are mounted, *all files* (with different users on machine A) map to
  nobody/nogroup. I even tried changing some options on machine A (like
  adding no_all_squash then re-exporting it) to no avail. I also tried
  manually mounting the filesystems using the "mount" command on machine
  C and the same thing happened. Before upgrading, the mounts were
  working correctly. On machine B with Ubuntu 11.10, they also work
  correctly.

  mount is version 2.20.1-1ubuntu3, nfs-common (which has
  /sbin/mount.nfs4) is version 1:1.2.5-3ubuntu2.
