Configuring Security and Authentication

Chapter 8 77

Configuring User Access Control

Another method for controlling access to the serial ports on the Digi CM unit is

the User Access Control configuration. You can set up this configuration either

globally (using the All Ports option) or per port.

It is not necessary to have users added to the system to assign rights.

However, for the permissions or restrictions to be enforced, the username

must match exactly. The username is case sensitive, and the application does

not recognize misspellings.

To add users, click on "System administration > Users administration". For

details about adding users, see "Administering Users" on page 69.

Note: Users do not need to be authenticated locally; they can be users on any

configured authentication server.

Using Access lists, you can add rights to a single user or to multiple users at

the same time. In addition, you can group multiple users and assign one,

some, or all these rights:

• Port access rights

• Port monitor rights

• Power management rights to an access list.

For more information, see "Create an Access list" on page 70.

This scenario shows a configuration with a restricted user: Joe does not have

access to the Sun server, while Mike does.

Your strategy for assigning rights to a port can include:

• Allowing <<Everyone>> access to a port and then restricting access to

certain users -or-

• Specifying each individual user and their specific rights to a port

JOE

MIKE
