libpam-unix2 lacks config file in /usr/share/pam-configs/unix2

[AlainKnaff]

Binary package hint: libpam-unix2

libpam-unix2 lacks config file in /usr/share/pam-configs/unix2. This means, that after manually adding libpam-unix2 into the PAM files, these changes will be lost when installing/uninstalling other PAM modules (such as winbind)

Description: Ubuntu 10.04.2 LTS
Release: 10.04
> apt-cache policy libpam-unix2
libpam-unix2:
  Installed: 1:2.4.1-4
  Candidate: 1:2.4.1-4

Expected:
- Installing libpam-unix2 should automatically add it to the files in /etc/pam.d . Installing/uninstalling other PAM packages (such as winbind) should not kick out libpam-unix2 config

What happens:
- When installing libpam-unix2, nothing is added automatically to /etc/pam.d . Moreover, any manual changes are lost after installing/uninstalling other PAM packages.
