Title:
  setcifsacl errors out, package missing idmap-plugin symlink

Status in cifs-utils package in Ubuntu:
  Confirmed
Status in cifs-utils package in Debian:
  Unknown

Bug description:
  # lsb_release -rd
  Description:	Ubuntu 14.04 LTS
  Release:	14.04

  # apt-cache policy cifs-utils
  cifs-utils:
    Installed: 2:6.0-1ubuntu2
    Candidate: 2:6.0-1ubuntu2

  
  The cifs-utils package is missing a symlink to the idmap plugin; attempting to run setcifsacl errors out like so:

  # setcifsacl -a
  "ACL:S-1-5-21-762712803-3572108623-4099884218-1003:ALLOWED/I/FULL"
  /data/test-file

  ERROR: unable to initialize idmapping plugin: /etc/cifs-utils/idmap-
  plugin: cannot open shared object file: No such file or directory

  
  The plugin is available, it's just a symlink needed to fix it even though idmap isn't being used (no winbind):

  # mkdir /etc/cifs-utils
  # ln -s /usr/lib/x86_64-linux-gnu/cifs-utils/idmapwb.so /etc/cifs-utils/idmap-plugin

  # setcifsacl -a
  "ACL:S-1-5-21-762712803-3572108623-4099884218-1003:ALLOWED/I/FULL"
  /data/test-file

  # getcifsacl /data/test-file
