Sun Management Center 3.6 User's Guide

Access Control Categories

The software offers the following ACL categories:

To understand ACL categories, you first need to understand Sun Management Center software users and groups. The following sections explain users and groups.

Sun Management Center Users

Sun Management Centerusers are valid UNIX users on the server host. As such, the system administrator has to add valid users into the file /var/opt/SUNWsymon/cfg/esusers. If a user's name is not in this file, that user cannot log into the Sun Management Center software.

General Users

The administrator has to add the list of user IDs for all users who need to log into Sun Management Center software. All users in this file have general access privileges, by default, unless the users are given additional privileges using the procedures described in To Grant a User esadm, esops, or esdomadm Privileges.

Any user who is part of the esusers file is known as a general user. Sun Management Center general users can, by default, perform the following functions:

Sun Management Center Superuser

The Sun Management Center superuser automatically belongs to all the groups that are described in the following sections. The Sun Management Center superuser has administrator privileges as described in Sun Management Center Administrators or esadm.

Sun Management Center Groups

The following groups are created by default on the server host during the Sun Management Center server setup:

In addition, all the Sun Management Center users belong to a hypothetical group, called ANYGROUP.

The listed groups must be defined on the machine where the Sun Management Center server layer is running. These groups do not need to be defined on other machines. These groups are described in greater detail in the sections that follow.


Note –

The listed groups are defined in the /etc/group file.


Sun Management Center Operators or esops

Sun Management Center software users that belong to the group esops are usually operator users. These operators run, monitor, and to some extent, configure parameters on the managed systems. esops can perform operations, including some operations that are allowed for general users:

Sun Management Center Administrators or esadm

Software users that belong to the group esadm can perform administrator operations. Administrator operations are a superset of the operations that can be performed by operator users as described in Sun Management Center Operators or esops. In addition to all the operations that operator users (esops) can perform, these administrator users (esadm) can perform the following operations:

Sun Management Center Domain Administrators or esdomadm

The users that belong to the group esdomadm can perform the following domain administrator operations:


Note –

Other than the privileges listed above, a user that belongs to esdomadm is just a general user, unless configured otherwise.


Administrator, Operator, and General Functions

The following table lists the different types of functions that users can do by default. A mark in a given cell indicates that the specified user can perform the listed function.

This table applies to all modules. Individual modules can also have specific restrictions, which are under the control of the module.

In Sun Management Center software, the above categories maintain inclusive relationships. This means that a user who has esadm privileges can do anything that a user who has esops privileges can do. An administrator can change the default permissions so that a user who has esops privileges can do more than a esadm user. Inclusive relationships mean that there is nothing in the software that makes one of esops, esadm, or esdomadm more powerful than either of the others.
