This configuration parameter specifies the suffix string or character to use in group names when automatically splitting up a group with large number of members.

Because group.bygid and group.byname NIS maps can often contain membership lists that exceed the 1024 limit for how much NIS data can be served to clients, the adnisd process will automatically truncate the membership list when this limit is reached. To allow the additional membership data to be retrieved, you can configure the Centrify Network Information Service to automatically split a large group into as many new groups as needed to deliver the complete membership list.

If you specify any value for the nisd.largegroup.suffix parameter, you enable the adnisd process to automatically split a large group into multiple new groups. When a group’s data size exceeds 1024 data limit, a new group is created. The new group name is formed using the original group name, followed by the string defined for the nisd.largegroup.suffix parameter and ending in a number that represents the numeric order of the new group created.

For example, if you have a large group named performix-worldwide-corp, and have defined the suffix string as “-all” and the maximum length for group names as 10, when the performix-worldwide-corp group membership is split into multiple groups, the groups are named as follows:


All of the new groups have the same group identifier (GID) as the original group. If the new group names would exceed the maximum length for group names on a platform, you can use the parameter to set the maximum length for the new groups created.

If this configuration parameter is not set, the adnisd process truncates the group membership list such that each group entry is under 1024 characters.
