# /etc/login.defs - Configuration control definitions for the login package.
#
# Three items must be defined: MAIL_DIR, ENV_SUPATH, and ENV_PATH.
# If unspecified, some arbitrary (and possibly incorrect) value will
# be assumed. All other items are optional - if not specified then
# the described action or option will be inhibited.
#
# Comment lines (lines beginning with "#") and blank lines are ignored.
#
# Modified for Linux. --marekm
# REQUIRED for useradd/userdel/usermod
# Directory where mailboxes reside, _or_ name of file, relative to the
# home directory. If you _do_ define MAIL_DIR and MAIL_FILE,
# MAIL_DIR takes precedence.
#
# Essentially:
# - MAIL_DIR defines the location of users mail spool files
# (for mbox use) by appending the username to MAIL_DIR as defined
# below.
# - MAIL_FILE defines the location of the users mail spool files as the
# fully-qualified filename obtained by prepending the user home
# directory before $MAIL_FILE
#
# NOTE: This is no more used for setting up users MAIL environment variable
# which is, starting from shadow 4.0.12-1 in Debian, entirely the
# job of the pam_mail PAM modules
# See default PAM configuration files provided for
# login, su, etc.
#
# This is a temporary situation: setting these variables will soon
# move to /etc/default/useradd and the variables will then be
# no more supported
MAIL_DIR /var/mail
#MAIL_FILE .mail

# Enable logging and display of /var/log/faillog login failure info.
# This option conflicts with the pam_tally PAM module.

# Enable display of unknown usernames when login failures are recorded.
#
# WARNING: Unknown usernames may become world readable.
# See #290803 and #298773 for details about how this could become a security
# concern
LOG_UNKFAIL_ENAB no
#
# Enable logging of successful logins
#
LOG_OK_LOGINS no
#
# Enable "syslog" logging of su activity - in addition to sulog file logging.
# SYSLOG_SG_ENAB does the same for newgrp and sg.

# If defined, all su activity is logged to this file.

#
# If defined, the command name to display when running "su -". For

#
SU_NAME su
#
# If defined, file which inhibits all the usual chatter during the login
# sequence. If a full pathname, then hushed mode will be enabled if the

# Terminal permissions
#
# TTYGROUP Login tty will be assigned this group ownership.
# TTYPERM Login tty will be set to this permission.
#
# If you have a "write" program which is "setgid" to a special group
# which owns the terminals, define TTYGROUP to the group number and
# TTYPERM to 0620. Otherwise leave TTYGROUP commented out and assign
# TTYPERM to either 622 or 600.
#
# In Debian /usr/bin/bsd-write or similar programs are setgid tty
# However, the default and recommended value for TTYPERM is still 0600
# to not allow anyone to write to anyone else console or terminal
# Users can still allow other people to write them by issuing
# the "mesg y" command.

# ERASECHAR Terminal ERASE character ('\010' = backspace).
# KILLCHAR Terminal KILL character ('\025' = CTRL/U).
# UMASK Default "umask" value.
#
# The ERASECHAR and KILLCHAR are used only on System V machines.
#
# UMASK is the default umask value for pam_umask and is used by
# useradd and newusers to set the mode of the new home directories.
# 022 is the "historical" value in Debian for UMASK
# 027, or even 077, could be considered better for privacy
# There is no One True Answer here : each sysadmin must make up his/her
# mind.
#
# If USERGROUPS_ENAB is set to "yes", that will modify this UMASK default value
# for private user groups, i. e. the uid is the same as gid, and username is
# the same as the primary group name: for these, the user permissions will be
# used as group permissions, e. g. 022 will become 002.
#
# Prefix these values with "0" to get octal, "0x" to get hexadecimal.

# Instead of the real user shell, the program specified by this parameter

#
# FAKE_SHELL /bin/fakeshell
#
# If defined, either full pathname of a file containing device names or

#CONSOLE console:tty01:tty02:tty03:tty04
#
# List of groups to add to the user's supplementary group set
# when logging in on the console (as determined by the CONSOLE

# Use with caution - it is possible for users to gain permanent
# access to these groups, even when not logged in on the console.
# How to do it is left as an exercise for the reader...

# If set to "yes", new passwords will be encrypted using the MD5-based
# algorithm compatible with the one used by recent releases of FreeBSD.
# It supports passwords of unlimited length and longer salt strings.
# Set to "no" if you need to copy encrypted passwords to other systems
# which don't understand the new algorithm. Default is "no".
#
# This variable is deprecated. You should use ENCRYPT_METHOD.
#
#MD5_CRYPT_ENAB no
#
# If set to MD5, MD5-based algorithm will be used for encrypting password
# If set to SHA256, SHA256-based algorithm will be used for encrypting password
# If set to SHA512, SHA512-based algorithm will be used for encrypting password
# If set to BCRYPT, BCRYPT-based algorithm will be used for encrypting password
# If set to YESCRYPT, YESCRYPT-based algorithm will be used for encrypting password
# If set to DES, DES-based algorithm will be used for encrypting password (default)
# MD5 and DES should not be used for new hashes, see crypt(5) for recommendations.
# Overrides the MD5_CRYPT_ENAB option
#
# Note: It is recommended to use a value consistent with
# the PAM modules configuration.
#
ENCRYPT_METHOD SHA512
#
# 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.
#
#SHA_CRYPT_MIN_ROUNDS 5000
#SHA_CRYPT_MAX_ROUNDS 5000
#
# 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.
# However, more CPU time and more memory will be needed to authenticate users
# if this value is increased.
#
# If not specified, a cost factor of 5 will be used.
# The value must be within the 1-11 range.
#
#YESCRYPT_COST_FACTOR 5
#
# The pwck(8) utility emits a warning for any system account with a home
