Managing User Mappings Between Windows and UNIX/Linux Users
You can dene mappings between Windows users in Active Directory and UNIX/Linux users in LDAP or NIS. The mapping 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 and mapping rules.
• 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 – Dene mappings between specic Windows users in Active Directory and the identical UNIX/Linux users in
LDAP or NIS. These specic mapping rules take precedence over automatic mapping. You can select the direction of the
mapping, which can go in one direction or both.
– Mapping is allowed in one direction:
* Windows user to a UNIX/Linux user
* UNIX/Linux user to a Windows user
– Mapping is allowed in both directions between a Windows user and a UNIX/Linux user.
User Mapping Policy and NAS Volume Security Style
User mapping permissions depend on the le security style for the NAS volume:
• NTFS security style – Permissions are controlled by Windows and NTFS. The UNIX/Linux user will adhere to the permissions of
the corresponding Windows user, regardless of the UNIX/Linux permission settings.
