You can create user mappings in the local storage system as well as use user mapping in the external IDMU domain to access shares across different systems. The following introduces how to set the mapping mode as well as timeout duration of the IDMU query, and search for the domain name.

Context

If you only use IDMU user mappings, you do not need to configure user mappings in the local storage system.

Procedure

  1. Log in to DeviceManager.
  2. Choose Provisioning > User Authentication > User Mapping.
  3. Click Set Mapping Parameters.
  4. Set the mapping parameters by referring toTable 4-2.

    • User mapping supported(rules set in IDMU): The system only supports user mappings in the IDMU domain.
    • User mapping supported(rules set in IDMU or local. IDMU preferred): When user mappings of a specific original user exist both in the system and the IDMU domain, the system preferentially uses the mapping in the IDMU domain.
