Title:
  sudo show predefine PAM prompt with some PAM Modules, no default sudo
  prompt

Status in sudo package in Ubuntu:
  In Progress

Bug description:
  I use libpam-krb5 for authentication, when I use sudo it show this
  prompt

  Password:

  Not the default of sudo

  [sudo] password for (user):

  But if it's set LANG=C (no locale) with module libpam-krb5 show the
  default prompt of sudo.

  With the module pam_unix (default of system) work without problems.

  Then the problem is in locale support of one of these packages. At
  check the source code of two I reached the conclusion.

  1. libpam-krb5 not support translations.

  2. sudo replaces the PAM prompt if this is "Password:" or translate of
  this. But sudo only check "Password:" translated on current language
  config (example "Contraseña:" on "es" locale).

  This bug not cause "real" problem but it may reveal the authentication
  system in use.

  This report has attached a (possible) patch of sudo for fix the bug.
