Title:
  permission denied for files i own on nfs4 with kerberos

Status in nfs-utils package in Ubuntu:
  Invalid

Bug description:
  Something new this morning on my system here... something which was
  most definitely working yesterday, and the day before that and last
  week, etc:

  nfs4_client $ hexdump: /usr/local/etc/Klinux_home_nsupdate+157+00000.key: Permission denied

  What am I demonstrating here?  Simply that trying to read from a file
  (/usr/local/etc/Klinux_home_nsupdate+157+00000.key) that I own mounted
  as a kerberized-nfs4 mount (on /usr/local) is returning EPERM yet I
  can read a file (/mnt/mp3/bad_mouth.mp3) from a different kerberized-
  nfs4 mount (/mnt/mp3) on a different filesystem with no problems.

  The collateral attached to this bug are from the nfs server, which is
  a Lucid machine.  I had to choose the client or the server to
  "ubuntu_bug" on and since the server is the "newest" link in the
  chain, I chose it.
