41 command verifies the integrity of the groups information\&. It checks that all entries in
44 have the proper format and contain valid data\&. The user is prompted to delete entries that are improperly formatted or which have other uncorrectable errors\&.
46 Checks are made to verify that each entry has:
56 the correct number of fields
67 a unique and valid group name
78 a valid group identifier
90 a valid list of members
102 a corresponding entry in the
111 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
113 command to correct the error\&.
115 The commands which operate on the
117 and /etc/gshadow files
118 are not able to alter corrupted or duplicated entries\&.

156 \fBMAX_MEMBERS_PER_GROUP\fR (number)
158 Maximum members per group entry\&. When the maximum is reached, a new group entry (line) is started in
160 (with the same name, same password, and same GID)\&.
162 The default value is 0, meaning that there are no limits in the number of members in a group\&.
164 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\&.
166 If you need to enforce such limit, you can use 25\&.
168 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\&.
