You can create user mappings in the local storage system as well as use user mappings in the external IDMU domain to access shares across systems. The operation enables you to set user mapping parameters.
Context
If only IDMU user mappings are used, you do not need to configure user mappings in the local storage system.
Procedure
- Choose Services > File Service > Authentication User > User Mappings.
- Click Set Mapping Parameter.
The Set Mapping Parameter page is displayed on the right.
- Enable Mapping Parameters and configure user mapping parameters.
Table 1 describes related parameters.
Table 1 Mapping parameters Parameter
Description
Mapping Mode
Indicates the global parameter of user mappings, including:
- Support only user mapping of this system: The system only supports user mappings created in this system.
- Support only user mapping in IDMU: The system only supports user mappings in the IDMU domain.
- Preferentially support user mapping in IDMU: When user mappings of a specified source user exist both in the system and the IDMU domain, the system preferentially uses the mapping in the IDMU domain.
- Preferentially support user mapping of this system: When user mappings of a specified source user exist both in the system and the IDMU domain, the system preferentially uses the mapping in this system.
IDMU Search Timeout Duration (s)
Indicates the timeout duration for the system to search for a specified user mapping in the IDMU domain.
[Value range]
5 to 120
IDMU Search DN
Indicates the benchmark directory where the system searches for a specified user mapping in the IDMU domain. The benchmark directory stores the information of user mappings.
[Value range]
The directory contains 0 to 255 characters.
Map to User with Same Name
Indicates whether to map to users with the same name. After this function is enabled, the system automatically maps UNIX users and Windows users with the same name.
Default UNIX User
When user mapping is enabled and a Windows user fails to be mapped, the Windows user will be mapped to this default UNIX user.
Map to User with Same Name, Default UNIX User, and Default Windows User are available only when Mapping Mode is set to Support only user mapping of this system, Preferentially support user mapping in IDMU, or Preferentially support user mapping of this system. IDMU Search Timeout Duration (s) and IDMU Search DN are available only when Mapping Mode is set to Support only user mapping in IDMU, Preferentially support user mapping in IDMU, or Preferentially support user mapping of this system.
