Managing User Mappings between Windows and UNIX/
Linux Users
You can define mappings between Windows users in Active Directory and UNIX/Linux users in LDAP or
NIS. This ensures that a Windows user inherits the UNIX/Linux user permissions, and a UNIX/Linux user
inherits the Windows user permissions, depending on the direction of the mapping and the NAS volume
security style.
User Mapping Policies
The user mapping policies include:
• Automatic mapping: Automatically map all Windows users in Active Directory to the identical UNIX/
Linux users in LDAP or NIS, and map all UNIX/Linux users to the identical Windows users. Automatic
mapping is disabled by default.
• Mapping rules: Define mappings between specific Windows users in Active Directory and the
corresponding UNIX/Linux users in LDAP or NIS. These specific mapping rules take precedence over
automatic mapping. You can select the direction of the mapping — the mapping can go in one
direction or both:
– Mapping is allowed in one direction:
* Windows users to a UNIX/Linux user
* UNIX/Linux user to a Windows user
– Mapping is allowed in both directions between Windows and UNIX/Linux users.

User Mapping Policy and NAS Volume Security Style
User mapping permissions depend on the file security style for the NAS volume:
