# This file is included from other service-specific PAM config files,

# used to change user passwords. The default is pam_unix.
# Explanation of pam_unix options:
#
# The "sha512" option enables salted SHA512 passwords. Without this option,
# the default is Unix crypt. Prior releases used the option "md5".
#
# The "obscure" option replaces the old `OBSCURE_CHECKS_ENAB' option in
# login.defs.
#
# See the pam_unix manpage for other options.
# As of pam 1.0.1-5, this file is managed by pam-auth-update by default.
# To take advantage of this, it is recommended that you configure any
# local modules either before or after the default block, and use
# pam-auth-update to manage selection of other modules. See

This is my /etc/pam. d/common- password after recently running another "aptitude upgrade", restoring the problematic line to /etc/pam. d/common- password
In this format, if I login as an LDAP user and type passwd, I get the following interaction
stemul@apps:~$ passwd
Enter login(LDAP) password:
passwd: password updated successfully
If I now change the line below
password [success=1 user_unknown=ignore default=die] pam_ldap.so use_authtok try_first_pass
to
password [success=1 user_unknown=ignore default=die] pam_ldap.so try_first_pass
and then try changing my password again ...
