I have nfs4 not working and guessing could it be same problem,... actually
after 12.04 to 14.04 upgrade it stopped to work and I belived it was
pam/ldap realatd problem,... can kindly look at and confirm that this is the
reason and I can wait kernel update ( or upgrade kerenel? ) to get NFS4
working.


Server:
  ApacheDS: ldap and kerberos
  MIT: kerberos client
  nfs-kernel

LOG say's while mounting from client:

This is OK whit server, so principal should work,...
sudo kinit -k -t /etc/krb5.keytab nfs/mpi1.kurrola.dy.fi@xxxxxxxxxx

Client: 
  MIT: kerberos client

joni@kaak:~$ sudo mount -a
mount.nfs4: access denied by server while mounting mpi1.kurrola.dy.fi:/

and log says at client:

Sep 24 18:37:53 kaak sudo:     joni : problem with defaults entries ; TTY=pts/2 ; PWD=/home/joni ; 
Sep 24 18:37:53 kaak sudo:     joni : TTY=pts/2 ; PWD=/home/joni ; USER=root ; COMMAND=/bin/mount -a
Sep 24 18:37:53 kaak sudo: pam_unix(sudo:session): session opened for user root by joni(uid=0)
Sep 24 18:37:54 kaak sudo: pam_unix(sudo:session): session closed for user root

This at client work's do principals should be ok.
 sudo kinit -k -t /etc/krb5.keytab nfs/kaak.kurrola.dy.fi@xxxxxxxxxx

Title:
  After upgrade to 3.13.0-35.62, rpc.gssd complains about missing
  /run/rpc_pipefs/gssd/clntXX/info

Status in “linux” package in Ubuntu:
  Fix Released
Status in “linux” source package in Trusty:
  Fix Committed

Bug description:
  The following changes in 3.13.0-35.62:
   * sunrpc: create a new dummy pipe for gssd to hold open
     - LP: #1327563
   * sunrpc: replace sunrpc_net->gssd_running flag with a more reliable check
     - LP: #1327563
   * nfs: check if gssd is running before attempting to use krb5i auth in SETCLIENTID call
     - LP: #1327563
  are causing rpc.gssd to fill syslog with messages of the form
  ERROR: can't open /run/rpc_pipefs/gssd/clntXX/info: No such file or directory

  The problem was discussed last December in https://bugzilla.redhat.com/show_bug.cgi?id=1037793
  where the resolution was to include the following three patches:

  http://marc.info/?l=linux-nfs&m=138624689302466&w=2
  http://marc.info/?l=linux-nfs&m=138624684502447&w=2
  http://marc.info/?l=linux-nfs&m=138624684502447&w=2

  These patches are already in the upstream kernel (since 3.14). I suggest cherry-picking them for 3.13. Commit hashes from the 3.14 branch:
