#

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

# and should contain a list of modules that define the services to be

# used to change user passwords. The default is pam_unix2 in combination

# with pam_pwcheck.

# The "nullok" option allows users to change an empty password, else

# empty passwords are treated as locked accounts.

#

# To enable Blowfish or MD5 passwords, you should edit

# /etc/default/passwd.

#

# Alternate strength checking for passwords should be configured

# in /etc/security/pam_pwcheck.conf.

#

# pam_make can be used to rebuild NIS maps after password change.

#
