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: 4012
Source: NfsService
Version: 6.0
Symbolic Name: ERR_NFS_LDAP_NOT_UNIQUE_GID
Message: Active Directory Domain Services(R) contains multiple groups which match attribute <%1>. Only one Windows(R) group should be assoicated with each UNIX GID. With multiple Windows groups associated with one UNIX GID, Server for NFS cannot determine which Windows group to use to grant access to files. Try removing the duplicate UNIX GID entries.

Resolve

Remove duplicate UNIX GID entries

Remove duplicate UNIX group identifier (GID) entries.

Note: For more information about removing GID 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.
