# /etc/pam.d/common-password - password-related modules common to all services
#
# 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_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".
#
# See the pam_unix manpage for other options.

# here are the per-package modules (the "Primary" block)
password    requisite                   pam_cracklib.so difok=2 minlen=8 maxrepeat=3 maxsequence=3 enforce_for_root
password    requisite                   pam_pwhistory.so remember=400 enforce_for_root
password    [success=1 default=ignore]  pam_unix.so sha512
# here's the fallback if no module succeeds
password    requisite                   pam_deny.so
# prime the stack with a positive return value if there isn't one already;
# this avoids us returning an error just because nothing sets a success code
# since the modules above will each just jump around
password    required                    pam_permit.so
# and here are more per-package modules (the "Additional" block)
