Client for NFS in Windows Server 2003 R2 does not support the PCNFS authentication mechanism (912032)

MORE INFORMATION

In earlier versions of Microsoft Windows Services for UNIX, Client for NFS supports authentication that is based on the PCNFS authentication mechanism. In these earlier versions, a PCNFS client sends the user name and the password in clear text to a PCNFS server to obtain the UNIX user identifier (UID) and the group identifier (GID). The UID and GID are required to identify UNIX users.

Windows Server 2003 R2 no longer supports this PCNFS authentication mechanism. However, the User Name Mapping service in Windows Server 2003 R2 can still use the password and the group files as sources for UNIX UIDs and GIDs.

The password and the group files in Windows Server 2003 R2 are sometimes referred to as PCNFS files for legacy purposes. However, these files do not depend on the PCNFS authentication mechanism. Windows Server 2003 R2 includes other authentication mechanisms such as Active Directory Lookup, User Name Mapping, and anonymous access.

For more information about these authentication mechanisms, see the Windows Server 2003 R2 Help documentation.
