nistbladm and Groups
In a Solaris-NIS+ environment, there are three types of groups:
UNIX groups. Information about UNIX groups is stored in the groups.org_dir table. Use nistbladm to administer UNIX group information.
Netgroups. Information about net groups is stored in the netgroups.org_dir table. Use nistbladm to administer net group information.
NIS+ groups. Information about NIS+ groups is stored in one or more tables in the groups_dir directory object. Use nisgrpadm to administer NIS+ group information.
Do not use nistbladm to administer NIS+ groups.
(See "Solaris Groups" for more information on the different types of groups and how to work with them.)
