57 must be a non\-negative decimal integer\&. This value must be unique, unless the
59 option is used\&. Values between 0 and 999 are typically reserved for system groups\&.
61 Any files that have the old group ID and must continue to belong to
62 \fIGROUP\fR, must have their group ID changed manually\&.

104 \fBMAX_MEMBERS_PER_GROUP\fR (number)
106 Maximum members per group entry\&. When the maximum is reached, a new group entry (line) is started in
108 (with the same name, same password, and same GID)\&.
110 The default value is 0, meaning that there are no limits in the number of members in a group\&.
112 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\&.
114 If you need to enforce such limit, you can use 25\&.
116 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\&.
