# This variable is deprecated. You should use ENCRYPT_METHOD instead.
#
#MD5_CRYPT_ENAB no

# MD5 and DES should not be used for new hashes, see crypt(5) for recommendations.
# Overrides the MD5_CRYPT_ENAB option
#
# Note: If you use PAM, it is recommended to use a value consistent with
# the PAM modules configuration.
#
#ENCRYPT_METHOD DES
#
# Only works if ENCRYPT_METHOD is set to SHA256 or SHA512.
#
# Define the number of SHA rounds.
# With a lot of rounds, it is more difficult to brute-force the password.
# However, more CPU resources will be needed to authenticate users if
# this value is increased.
#
# If not specified, the libc will choose the default number of rounds (5000),
# which is orders of magnitude too low for modern hardware.
# The values must be within the 1000-999999999 range.
# If only one of the MIN or MAX values is set, then this value will be used.
# If MIN > MAX, the highest value will be used.

# Define the number of BCRYPT rounds.
# With a lot of rounds, it is more difficult to brute-force the password.
# However, more CPU resources will be needed to authenticate users if
# this value is increased.
#
# If not specified, 13 rounds will be attempted.
# If only one of the MIN or MAX values is set, then this value will be used.
# If MIN > MAX, the highest value will be used.
#
#BCRYPT_MIN_ROUNDS 13
#BCRYPT_MAX_ROUNDS 13
#
# Only works if ENCRYPT_METHOD is set to YESCRYPT.

# Define the YESCRYPT cost factor.
# With a higher cost factor, it is more difficult to brute-force the password.

# If not specified, a cost factor of 5 will be used.
# The value must be within the 1-11 range.

#YESCRYPT_COST_FACTOR 5
#
# List of groups to add to the user's supplementary group set
# when logging in from the console (as determined by the CONSOLE

#
# Use with caution - it is possible for users to gain permanent

# How to do it is left as an exercise for the reader...
#
#CONSOLE_GROUPS floppy:audio:cdrom
#
# Should login be allowed if we can't cd to the home directory?
# Default is no.
#
DEFAULT_HOME yes
#
# The pwck(8) utility emits a warning for any system account with a home
# directory that does not exist. Some system accounts intentionally do
# not have a home directory. Such accounts may have this string as
# their home directory in /etc/passwd to avoid a spurious warning.

#USERDEL_CMD /usr/sbin/userdel_local
#
# Enable setting of the umask group bits to be the same as owner bits
# (examples: 022 -> 002, 077 -> 007) for non-root users, if the uid is
# the same as gid, and username is the same as the primary group name.
#
# This also enables userdel(8) to remove user groups if no members exist.
#
USERGROUPS_ENAB yes
#
# If set to a non-zero number, the shadow utilities will make sure that
# groups never have more than this number of users on one line.
# This permits to support split groups (groups split into multiple lines,
# with the same group ID, to avoid limitation of the line length in the
# group file).
#
# 0 is the default value and disables this feature.
#
#MAX_MEMBERS_PER_GROUP 0
#
# If useradd(8) should create home directories for users by default (non
# system users only).
# This option is overridden with the -M or -m flags on the useradd(8)
# command-line.
#
#CREATE_HOME yes
#
# Force use shadow, even if shadow passwd & shadow group files are
# missing.
#
#FORCE_SHADOW yes
#
# Allow newuidmap and newgidmap when running under an alternative
# primary group.
#
#GRANT_AUX_GROUP_SUBIDS yes
#
# Prevents an empty password field to be interpreted as "no authentication
# required".
# Set to "yes" to prevent for all accounts
# Set to "superuser" to prevent for UID 0 / root (default)
# Set to "no" to not prevent for any account (dangerous, historical default)
PREVENT_NO_AUTH superuser

# /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 "md5" option enables MD5 passwords. Without this option, the
# default is Unix crypt.
#
# The "obscure" option replaces the old `OBSCURE_CHECKS_ENAB' option in
# login.defs.
#
# See the pam_unix manpage for other options.
# As of pam 1.0.1-6, 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
# pam-auth-update(8) for details.
# here are the per-package modules (the "Primary" block)
password [success=1 default=ignore] pam_unix.so obscure
# 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)
# end of pam-auth-update config
