  When attempting to clear NFS uid/gid cache I ran nfsidmap -c

  expected Result
  no response, nfsidmap does not return anything if it completes properly

  [root@quebec ~]# nfsidmap -c
  [root@quebec ~]#

  What did happen

  root@u1404vm:~# nfsidmap -c
  nfsidmap: fopen(/proc/keys) failed: No such file or directory

  I checked /proc and the /proc/key-users file and the
  /proc/sys/kernel/keys directory were there.

  I Looked up Kernel Key Management and saw that /proc/keys was needed
  to hold the key pairs used by the kernel.

   From Google'ng the following kernel option needs to be enabled


  or /proc/keys does not get created.

  I checked /boot/config-3.13.0-24-generic and that option is not

  I checked this on both Centos 6.5/7 and Mageia and they are enabled
  and /proc/keys exist, nfsidmap -c works.
