comment: |-
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.
If set to yes, userdel will remove the user's group if it contains no
more members, and useradd will create by default a group with the name
of the user.Default Configuration

This option conflicts with the pam_tally PAM module.
LOG_UNKFAIL_ENAB:

comment: |-
Enable display of unknown usernames when login failures are recorded.
WARNING: Unknown usernames may become world readable.

concern
LOG_OK_LOGINS:
value: 'no'
comment: |-
Enable logging of successful logins
SYSLOG_SU_ENAB:
value: 'yes'
comment: |-
Enable "syslog" logging of su activity - in addition to sulog file logging.
SYSLOG_SG_ENAB does the same for newgrp and sg.
SYSLOG_SG_ENAB:

SULOG_FILE:
value: /var/log/sulog
enabled: false
comment: |-
If defined, all su activity is logged to this file.
TTYTYPE_FILE:

comment: |-
If defined, file which maps tty line to TERM environment parameter.
Each line of the file is in a format something like "vt100 tty01".
FTMP_FILE:
value: /var/log/btmp
comment: |-
If defined, login failures will be logged here in a utmp format
last, when invoked as lastb, will read /var/log/btmp, so...
SU_NAME:
value: su
comment: |-
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".
HUSHLOGIN_FILE:
value: .hushlogin
comment: |-
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.
ENV_SUPATH:

ENV_PATH:

TTYGROUP:
value: tty
comment: |-
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.
TTYPERM:
value: '0600'
ERASECHAR:
value: '0177'
comment: |-
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.
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.
KILLCHAR:
value: '025'
UMASK:

LOGIN_RETRIES:

comment: |-
Max number of login retries if password is bad. This will most likely be
overriden by PAM, since the default pam_unix module has it's own built
in of 3 retries. However, this is a safe fallback in case you are using
an authentication module that does not enforce PAM_MAXTRIES.
LOGIN_TIMEOUT:
value: 60
comment: Max time in seconds for login
CHFN_RESTRICT:
value: rwh
comment: |-
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".
DEFAULT_HOME:

Default in no.
USERDEL_CMD:

comment: |-
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).
USERGROUPS_ENAB:
value: 'yes'
comment: |-
If set to yes, userdel will remove the user's group if it contains no
more members, and useradd will create by default a group with the name
of the user.
Other former uses of this variable such as setting the umask when
user==primary group are not used in PAM environments, such as Debian
FAKE_SHELL:
value: /bin/fakeshell
enabled: false
comment: |-
Instead of the real user shell, the program specified by this parameter
will be launched, although its visible name (argv[0]) will be the shell's.
The program may do whatever it wants (logging, additional authentification,
banner, ...) before running the actual shell.
CONSOLE:
value: /etc/consoles
enabled: false
comment: |-
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.
This variable is used by login and su.
CONSOLE_GROUPS:
value: 'floppy:audio:cdrom'
enabled: false
comment: |-
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...
This variable is used by login and su.
MD5_CRYPT_ENAB:
value: 'no'
enabled: false
comment: |-
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.
ENCRYPT_METHOD:
value: SHA512
comment: |-
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.
SHA_CRYPT_MIN_ROUNDS:
value: 5000
enabled: false
comment: |-
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.
If MIN > MAX, the highest value will be used.
