OSF DCE Application Development Guide--Core Components

RPC and Other DCE Components
• NSI object attribute
The object attribute stores a list of one or more object UUIDs. Whenever a server
exports any object UUIDs to a server entry, the server entry contains an object
attribute as well as a binding attribute. When a client imports from that entry, the
import operation returns an object UUID from the list stored in the object attribute.
• NSI group attribute
The group attribute stores the entry names of the members of a single group. This
attribute identifies a directory service entry as an RPC group.
• NSI profile attribute
The profile attribute stores a set of profile elements. This attribute identifies a
directory service entry as an RPC profile.
Figure 14-7 represents the correspondence between NSI attributes and the different
directory service entries: server entries, groups, and profiles.

Any directory service entry can contain any combination of the four NSI attributes.
However, to facilitate administrating directory service entries, avoid creating binding,
group, and profile attributes in the same entry. Instead, use distinct directory service
entries for server entries, groups, and profiles. The object attribute, in contrast, is
designed as an adjunct to another NSI attribute, especially the binding attribute.
