CONFIGURATION

       The following configuration variables in /etc/login.defs change the
       behavior of this tool:

       GID_MAX (number), GID_MIN (number)
           Range of group IDs used for the creation of regular groups by
           useradd, groupadd, or newusers.

       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)
               .     ,      .    ,    -1 (     ).

       PASS_MIN_DAYS (number)
                .         .    ,    -1 (     ).

       PASS_WARN_AGE (number)
                    .   ,      ,       .    ,   .

       SYS_GID_MAX (number), SYS_GID_MIN (number)
           Range of group IDs used for the creation of system groups by
           useradd, groupadd, or newusers.

       SYS_UID_MAX (number), SYS_UID_MIN (number)
           Range of user IDs used for the creation of system users by useradd
           or newusers.

       UID_MAX (number), UID_MIN (number)
           Range of user IDs used for the creation of regular users by useradd
           or newusers.

       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 pam_umask as the default umask value.
