#
# 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.

# 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

# In Debian /usr/bin/bsd-write or similar programs are setgid tty

# 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

# 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

# Which fields may be changed by regular users using chfn - use

#USERDEL_CMD /usr/sbin/userdel_local#
# Enable setting of the umask group bits to be the same as owner bits

# the same as gid, and username is the same as the primary group name.
#
# If set to yes, userdel will remove the users group if it contains no
# more members, and useradd will create by default a group with the name
# of the user.
#
USERGROUPS_ENAB yes#
# Instead of the real user shell, the program specified by this parameter
# will be launched, although its visible name (argv[0]) will be the shells.
# The program may do whatever it wants (logging, additional authentification,
# banner, ...) before running the actual shell.

# FAKE_SHELL /bin/fakeshell#
# If defined, either full pathname of a file containing device names or
# a : delimited list of device names. Root logins will be allowed only

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

# Set to no if you need to copy encrypted passwords to other systems
# which dont 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 DES, DES-based algorithm will be used for encrypting password (default)
# Overrides the MD5_CRYPT_ENAB option
#
# Note: It is recommended to use a value consistent with
# the PAM modules configuration.
#
ENCRYPT_METHOD SHA512#
# Only used 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 forcing the password.
# But note also that it more CPU resources will be needed to authenticate
# users.
#
# If not specified, the libc will choose the default number of rounds (5000).
# The values must be inside the 1000-999999999 range.
# If only one of the MIN or MAX values is set, then this value will be used.
