ID Manager configures and monitors a pool of resource IDs that a client can use to establish a host session, thereby eliminating the need for administrators to create configurations for every client. Depending on the type of terminal or printer, these resource IDs may represent addresses or identifiers as required.You can use ID Manager with the IBM3270 and IBM5250 terminals and printers.To use ID Manager, you'll need access to a centralized management server with ID Manager configured.
Note: For detailed instructions that show how to set up ID Management, see "Set Up ID Management for Reflection Desktop Sessions" in the Reflection Deployment Guide.
