System Administration Guide: Naming and Directory Services (NIS+)

Deleting an NIS+ Group

To delete an NIS+ group, you must have destroy rights to the groups_dir directory in the group's domain. Use the -d option:

nisgrpadm -d group-name

If the default domain is set properly, you don't have to fully-qualify the group name. However, you should check first (use nisdefaults), because you could unintentionally delete a group in another domain. The example below deletes the group.

salesmaster% nisgrpadm -d
Group `' destroyed.
