Configuration

A folder that is shared by using both the Server Message Block (SMB) protocol and the Network File System (NFS) protocol has Anonymous logon or Unmapped Unix User Access (UUUA) enabled.

Users might not be able to access the same files by using the SMB protocol as they can by using the NFS protocol.

Use Share and Storage Management to configure Services for Network File System to use an appropriate identity mapping solution for mapping Windows accounts to non-Windows accounts.

Access to file servers that are running the Windows operating system requires user and group identities in Windows. However, NFS access is based on UNIX-style user and group identities. To enable users to access NFS shares, you can set up identity mapping. Services for NFS can retrieve identity mappings from Active Directory Domain Services if the schema includes the appropriate UNIX-style identities.

Membership in the Administrators group is required to complete this procedure.

  1. In Administrative Tools, click Share and Storage Management.

  2. In the Actions pane, click Edit NFS Configuration.

  3. In Services for NFS Configuration, click Select an Identity Mapping Solution, and then click Identity Mapping Wizard.

  4. In Identity Mapping Solution, click Retrieve identity mappings from Active Directory, and then proceed through the wizard.
