CREATE_HOME (boolean) | CREATE_HOME (boolean) | ||
Indicate if a home directory should be created by default for new users. | |||
This setting does not apply to system users, and can be overridden on the command line. | |||
GID_MAX (number), GID_MIN (number) | |||
Range of group IDs used for the creation of regular groups by useradd, groupadd, or newusers. | |||
The default value for GID_MIN (resp. GID_MAX) is 500 (resp. 60000). | |||
MAIL_DIR (string) | |||
The mail spool directory. This is needed to manipulate the mailbox when its corresponding user account is modified | |||
or deleted. If not specified, a compile-time default is used. | |||
MAIL_FILE (string) | |||
Defines the location of the users mail spool files relatively to their home directory. | |||
The MAIL_DIR and MAIL_FILE variables are used by useradd, usermod, and userdel to create, move, or delete the user´s | |||
mail spool. | |||
If MAIL_CHECK_ENAB is set to yes, they are also used to define the MAIL environment variable. | |||
MAX_MEMBERS_PER_GROUP (number) | |||
Maximum members per group entry. When the maximum is reached, a new group entry (line) is started in /etc/group | |||
(with the same name, same password, and same GID). | |||
The default value is 0, meaning that there are no limits in the number of members in a group. | |||
This feature (split group) permits to limit the length of lines in the group file. This is useful to make sure that | |||
lines for NIS groups are not larger than 1024 characters. | |||
If you need to enforce such limit, you can use 25. | |||
Note: split groups may not be supported by all tools (even in the Shadow toolsuite). You should not use this | |||
variable unless you really need it. | |||
PASS_MAX_DAYS (number) | |||
The maximum number of days a password may be used. If the password is older than this, a password change will be | |||
forced. If not specified, -1 will be assumed (which disables the restriction). | |||
PASS_MIN_DAYS (number) | |||
The minimum number of days allowed between password changes. Any password changes attempted sooner than this will | |||
be rejected. If not specified, -1 will be assumed (which disables the restriction). | |||
PASS_WARN_AGE (number) | |||
The number of days warning given before a password expires. A zero means warning is given only upon the day of | |||
expiration, a negative value means no warning is given. If not specified, no warning will be provided. | |||
SYS_GID_MAX (number), SYS_GID_MIN (number) | |||
Range of group IDs used for the creation of system groups by useradd, groupadd, or newusers. | |||
The default value for SYS_GID_MIN (resp. SYS_GID_MAX) is 201 (resp. GID_MIN-1). | |||
SYS_UID_MAX (number), SYS_UID_MIN (number) | |||
Range of user IDs used for the creation of system users by useradd or newusers. | |||
The default value for SYS_UID_MIN (resp. SYS_UID_MAX) is 201 (resp. UID_MIN-1). | |||
UID_MAX (number), UID_MIN (number) | |||
Range of user IDs used for the creation of regular users by useradd or newusers. | |||
The default value for UID_MIN (resp. UID_MAX) is 500 (resp. 60000). | |||
UMASK (number) | |||
The file mode creation mask is initialized to this value. If not specified, the mask will be initialized to 022. | |||
useradd and newusers use this mask to set the mode of the home directory they create | |||
It is also used by login to define users´ initial umask. Note that this mask can be overridden by the user´s GECOS | |||
line (if QUOTAS_ENAB is set) or by the specification of a limit with the K identifier in limits(5). | |||
USERGROUPS_ENAB (boolean) | |||
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. | |||
