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

NIS+ Group Syntax

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.
