#
# 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
#
# Delay in seconds before being allowed another attempt after a login failure
#
FAIL_DELAY 3
#
# Enable display of unknown usernames when login failures are recorded.
#
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.
#
SYSLOG_SU_ENAB yes
SYSLOG_SG_ENAB yes
#
# If defined, either full pathname of a file containing device names or
# a ":" delimited list of device names. Root logins will be allowed only
# upon these devices.
#
CONSOLE /etc/securetty
#CONSOLE console:tty01:tty02:tty03:tty04
#
# If defined, all su activity is logged to this file.
#
#SULOG_FILE /var/log/sulog
#
# If defined, file which maps tty line to TERM environment parameter.
# Each line of the file is in a format something like "vt100 tty01".
#
#TTYTYPE_FILE /etc/ttytype
#
# If defined, the command name to display when running "su -". For
# example, if this is defined as "su" then a "ps" will display the
# command is "-su". If not defined, then "ps" would display the
# name of the shell actually being run, e.g. something like "-sh".
#
SU_NAME su
#
# *REQUIRED*
# Directory where mailboxes reside, _or_ name of file, relative to the
# home directory. If you _do_ define both, MAIL_DIR takes precedence.
#
MAIL_DIR /var/spool/mail
#
# 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
# user's name or shell are found in the file. If not a full pathname, then
# hushed mode will be enabled if the file exists in the user's home directory.
#
HUSHLOGIN_FILE .hushlogin
#HUSHLOGIN_FILE /etc/hushlogins
#
# *REQUIRED* The default PATH settings, for superuser and normal users.

# 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.

TTYGROUP tty
TTYPERM 0600
#
# Login configuration initializations:
#
# 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.
# The ULIMIT is used only if the system supports it.
# (now it works with setrlimit too; ulimit is in 512-byte units)
#
# Prefix these values with "0" to get octal, "0x" to get hexadecimal.

ERASECHAR 0177
KILLCHAR 025

# Password aging controls:
#
# PASS_MAX_DAYS Maximum number of days a password may be used.
# PASS_MIN_DAYS Minimum number of days allowed between password changes.
# PASS_WARN_AGE Number of days warning given before a password expires.
#
PASS_MAX_DAYS 99999

# Max number of login retries if password is bad

# Max time in seconds for login
#
LOGIN_TIMEOUT 60
#
# Which fields may be changed by regular users using chfn - use
# any combination of letters "frwh" (full name, room number, work
# phone, home phone). If not defined, no changes are allowed.
# For backward compatibility, "yes" = "rwh" and "no" = "frwh".
#
CHFN_RESTRICT rwh
#
# List of groups to add to the user's supplementary group set
# when logging in on the console (as determined by the CONSOLE
# setting). Default is none.
#
# 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...
#
#CONSOLE_GROUPS floppy:audio:cdrom
#
# Should login be allowed if we can't cd to the home directory?
# Default in no.
#
DEFAULT_HOME yes
#
# If defined, this command is run when removing a user.
# It should remove any at/cron/print jobs etc. owned by
# the user to be removed (passed as the first argument).
#
#USERDEL_CMD /usr/sbin/userdel_local
#
# When prompting for password without echo, getpass() can optionally
# display a random number (in the range 1 to GETPASS_ASTERISKS) of '*'
# characters for each character typed. This feature is designed to
# confuse people looking over your shoulder when you enter a password :-).
# Also, the new getpass() accepts both Backspace (8) and Delete (127)
# keys to delete previous character (to cope with different terminal
# types), Control-U to delete all characters, and beeps when there are
# no more characters to delete, or too many characters entered.
#
# Setting GETPASS_ASTERISKS to 1 results in more traditional behaviour -
# exactly one '*' displayed for each character typed.
#
# Setting GETPASS_ASTERISKS to 0 disables the '*' characters (Backspace,
# Delete, Control-U and beep continue to work as described above).
#
# Setting GETPASS_ASTERISKS to -1 reverts to the traditional getpass()
# without any new features. This is the default.
#
GETPASS_ASTERISKS 0
#
# 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 to remove user groups if no members exist.
#
USERGROUPS_ENAB yes
