|System Administration Guide: Naming and Directory Services (NIS+)|
NIS+ groups can have three types of members: explicit, implicit, and recursive; and three types of nonmembers, also explicit, implicit, and recursive. These member types are used when adding or removing members of a group as described in nisgrpadm Command.
Implicit. All the NIS+ principals who belong to an NIS+ domain. They are identified by their domain name, preceded by the * symbol and a dot. The operation you select applies to all the members in the group.
Recursive. All the NIS+ principals that are members of another NIS+ group. They are identified by their NIS+ group name, preceded by the @ symbol. The operation you select applies to all the members in the group.
Nonmembers are identified by a minus sign in front of their name:
The order in which inclusions and exclusions are entered does not matter. Exclusions always take precedence over inclusions. Thus, if a principal is a member of an included implicit domain and also a member of an excluded recursive group, then that principal is not included.
Thus, when using the nisgrpadm command, you can specify group members and nonmembers as shown in Table 17-2.
