Solaris Groups and NIS+ Groups

The Solaris NIS+ environment defines three kinds of groups: UNIX groups, net groups, and NIS+ groups.

• UNIX groups. A UNIX group is simply a collection of users who are given additional UNIX access permissions. In an NIS+ namespace, UNIX group information is stored in the group table located in the org_dir directory object (group.org_dir). See Chapter 19, Administering NIS+ Tables for information on how to add, modify, or delete members of a UNIX group.

• Net groups. A net group is a group of machines and users that have permission to perform remote operations on other machines. In an NIS+ namespace, net groups information is stored in the netgroup table located in the org_dir directory object (netgroup.org_dir). See Chapter 19, Administering NIS+ Tables for information on how to add, modify, or delete members of a net groups.

• NIS+ groups. An NIS+ group is a set of NIS+ users that are assigned specific access rights to NIS+ objects, usually for the purpose of administering the namespace. NIS+ group information is stored in tables located in the groups_dir directory object.
