Title:
  cifs-utils apparently installed but not working, reinstalling fixes
  (no sign of filesystem corruption)

Status in cifs-utils package in Ubuntu:
  New

Bug description:
  Something unusual happened on a fresh Ubuntu 13.10.

  This might not be a mount.cifs bug but a bug elsewhere.

  # Expected behavior

  This command worked on 12.10 :

  sudo mount -f cifs '//someip/d$' /home/me/validmountpoint -o
  credentials=/home/me/validcredentialfile.txt,uid=me

  # Observed behavior

  On a fresh 13.10 it said:

  mount : mauvais type de système de fichiers, option erronée, superbloc erroné
          sur //192.168.46.45/d$, page de code ou programme auxiliaire manquant, ou autre erreur
         (pour plusieurs système de fichiers (NFS ou CIFS par exemple), un
          programme /sbin/mount.<type> auxiliaire pourrait être nécessaire)
         Dans quelques cas certaines informations sont utiles dans le journal
          système — essayez « dmesg | tail » ou quelque chose du genre

  Issuing dmesg | tail:

  [ 3086.625796] Key type cifs.spnego registered

  # cifs-utils ? Already installed

  The net says: install cifs-utils. But:

  sudo aptitude install cifs-utils

  Aucun paquet ne va être installé, mis à jour ou enlevé.
  0 paquets mis à jour, 0 nouvellement installés, 0 à enlever et 0 non mis à jour.
  Il est nécessaire de télécharger 0 o d'archives. Après dépaquetage, 0 o seront utilisés.

  Indeed it is already installed:

  dpkg -l "cifs-utils"

  Souhait=inconnU/Installé/suppRimé/Purgé/H=à garder

  ii  cifs-utils                       2:6.0-1ubuntu2        amd64                 Common Internet File System utilities

  # Command still fails, what to do ?

  I asked aptitude, in interactive mode, to reinstall cifs-utils.

  (Lecture de la base de données... 164854 fichiers et répertoires déjà installés.)
  Préparation du remplacement de cifs-utils 2:6.0-1ubuntu2 (en utilisant .../cifs-utils_2%3a6.0-1ubuntu2_amd64.deb) ...
  Dépaquetage de la mise à jour de cifs-utils ...
  Traitement des actions différées (« triggers ») pour « man-db »...
  Paramétrage de cifs-utils (2:6.0-1ubuntu2) ...
  Appuyez sur Entrée pour continuer.

  Then the command works.

  dmesg | tail has exactly same output as before.

  # Additional information

  One might suspect some kind of incomplete install of package.
  Besides this, system work normally, was well used for two days without specific problem.
  Hardware is sane, no sign of filesystem corruption, UBuntu 12.10 still there and working.

  Any idea why it could have failed ?

  lsb_release -rd

  Description:	Ubuntu 13.10
  Release:	13.10

  The command below is typed after reinstalling the package. Yet
  aptitude said it was same version.

  LC_ALL=C apt-cache policy cifs-utils

  cifs-utils:
    Installed: 2:6.0-1ubuntu2
