The checks for correct number of fields and unique group name are fatal\&. If an entry has the wrong number of fields, the user will be prompted to delete the entire line\&. If the user does not answer affirmatively, all further checks are bypassed\&. An entry with a duplicated group name is prompted for deletion, but the remaining checks will still be made\&. All other errors are warnings and the user is encouraged to run the
|

\fBgroupmod\fR

The commands which operate on the

By default,

\fBgrpck\fR
|

operates on

/etc/group

The following configuration variables in

change the behavior of this tool:
|

.PP
|
||
\fBMAX_MEMBERS_PER_GROUP\fR (number)
|
||
.RS 4
|
||
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)\&.
|
||
.sp
|
||
The default value is 0, meaning that there are no limits in the number of members in a group\&.
|
||
.sp
|
||
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\&.
|
||
.sp
|
||
If you need to enforce such limit, you can use 25\&.

.sp

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\&.
