The naming model of NIS+ is based upon a tree structure. Each node in the tree corresponds to an NIS+ object. There are six types of NIS+ objects: directory, table, group, link, entry, and private.
NIS+ Directory Object Each NIS+ namespace will have at least one NIS+ directory object. An NIS+ directory is like a UNIX file system direc- tory which contains other NIS+ objects including NIS+ direc- tories. The NIS+ directory that forms the root of the NIS+ namespace is called the root directory. There are two spe- cial NIS+ directories: org_dir and groups_dir. The org_dir directory consists of all the system-wide administration tables, such as passwd, hosts, and mail_aliases. The groups_dir directory consists of NIS+ group objects which are used for access control. The collection of org_dir, groups_dir and their parent directory is referred to as an NIS+ domain. NIS+ directories can be arranged in a tree- like structure so that the NIS+ namespace can match the organizational or administrative hierarchy.
