Overview of Names

A name is an entity to which you can assign IDs. There are several types of names:

The optimal choice for your site depends on a number of factors:

Using User Names

Assigning IDs to user names ensures that specific users receive specific IDs, no matter which computer they use. With this approach, all users must provide a user name when accessing a viewer or printer applet.

For Terminal Viewers, a user name prompt appears if the Authentication Type specified in Presentation Manager requires a user name. Alternatively, you can disable user authentication, but you must then assign the presentations to specific users or groups to ensure that a user name prompt appears.

The available user names are determined by the directory service used by Management & Control Services (MCS).

Using IP Addresses or DNS Names

Assigning IDs to IP addresses or DNS names ensures that specific computers receive specific IDs, no matter which user accesses a viewer or printer applet using that computer. This can be an effective way to manage IDs without setting up an account for each user in the directory service.

With this approach, you can disable authentication and assign the presentation to everyone, or you can still prompt for a user name. However, the user name does not determine which IDs are available. Instead, the computer's IP address or DNS name determines which IDs to use.

Using Address Pools

Assigning IDs to address pools makes IDs available on a first-come, first-served basis to all clients that use a particular configuration. Any user at any computer can open as many sessions as desired until all of the addresses assigned to the address pool are in use.

You can still limit certain IDs to certain users by creating a number of different address pools. For example, you could create a different address pool for each department at your company (Accounting, Sales, etc.). You would then create a different configuration for each address pool, and provide each department with access to only the appropriate configuration.

By assigning IDs to address pools, you can disable authentication and assign the presentation to everyone, or you can still prompt for a user name. However, the user name does not determine which IDs are available. Instead, the address pool name specified in the configuration determines which IDs are available, and each user who accesses a viewer or printer applet gets the first available ID in the associated pool.
