Configuration

Services for Network File System is configured to use the User Name Mapping Service.

The compatibility of Services for Network File System is limited because it performs identity mapping by using a deprecated, proprietary technology instead of by using an identity mapping solution based on the RFC 2307 industry standard.

Implement an RFC 2307-based identity mapping solution such as Active Directory Domain Services (AD DS), Active Directory Lightweight Domain Services (AD LDS), or other compliant Lightweight Directory Access Protocol (LDAP) stores.

Membership in the local Administrators group, or equivalent, on the server that you plan to configure, is the minimum required to complete this procedure.

  1. Open an elevated Command Prompt window. (Click Start, point to All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator.)

  2. Type nfsadmin mapping to display and configure identity mapping settings.

  3. To configure identity mapping settings for an LDAP server, type nfsadmin mapping config adlookup=yes addomain=domainname.
