Server for NFS enables you to control access by users and groups to Services for Network File System (NFS) resources. A connection to an Light Directory Access Protocol (LDAP) server allows Server for NFS to query Windows-UNIX user account mappings and grant file access to a user.

Event Details

Product: Windows Operating System
ID: 4011
Source: NfsService
Version: 6.0
Symbolic Name: ERR_NFS_LDAP_NOT_UNIQUE_UID
Message: Active Directory Domain Services(R) contains multiple users which match attribute <%1>. Only one Windows(R) user should be assoicated with each UNIX UID. With multiple Windows users associated with one UNIX UID, Server for NFS cannot determine which Windows user is requesting access to files. No Windows users associated with the same UNIX UID will be able to access files through Server for NFS. Try removing the duplicate UNIX UID entries.

Resolve

Remove duplicate UNIX UID entries

Remove duplicate UNIX user identifier (UID) entries.

Note: For more information about removing UID entries, see your LDAP vendor's documentation.

Verify

To verify that Services for Network File System (NFS) is properly configured for retrieving Windows-UNIX identity mappings from the LDAP service:

  1. Open a command prompt with elevated privileges and type nfsadmin mapping config.
  2. Verify that the Mapping Server field in the list displays your installed LDAP service.
