H.1 About System Users and Groups

“Regular” network users rely on network services. System users and groups support those services.

Some NetWare administrators are concerned about the number of system users and groups on an OES server. They wonder what functions system users perform, why there are “so many” of them, and how they impact licensing and network security.

The answers to these and other questions are found in the sections that follow.

H.1.1 Types of OES System Users and Groups

The users and groups that support OES services can be grouped into the three types shown in Table H-1.
