Set up and use host access IDs so that you can use a single session configuration file for multiple clients to establish multiple sessions with a host.

An ID is connection data that is unique for an individual session with a host. The type of connection data and available properties for an ID depend on the host type with which it will be used.


You can set up and use host access IDs so that you don't have to maintain unique connection data in individual configuration or session files. With host access IDs, you use a single file for multiple clients that can establish multiple sessions with a host. When a client is started, it gets its ID from Management & Control Services (MCS) and uses the ID to connect to the host. MCS keeps track of the IDs that are in use.

Before You Start

You need to decide which of several types of pools to use. The type of pool you should select depends on how you want to control access to the host.

For example, to allocate certain IDs to certain computers, you assign IDs to IP addresses or DNS names. To allocate certain IDs to certain users, you assign IDs to user names. Before you can create pools based on your directory service or user names, you must set up your directory service in MCS.

Your selection may also depend on restrictions in the client application. In addition, depending on your host type, the IDs may need to map to existing IDs on the host. For information about restrictions for your product, refer to your product documentation.


Following are the main steps you need to complete for this How-To:

  1. Create pools of IDs.

  2. Assign IDs to pools.

  3. Create an application or session configuration that obtains its ID from MCS.
