NFS Account Mapping Whitepaper:

This paper covers Network File System (NFS) account mapping and the deployment in Windows Server 2008 R2. NFS is a network file sharing protocol that allows remote access to files over a network. NFS implementations include an NFS server component, which enables the sharing of files for use by other networked computers, and an NFS client component, which enables computers to access files shared by NFS servers. The Services for NFS role service in Windows Server provides the ability to function as an NFS server. Windows and UNIX operating systems use different account and security systems. Windows operating systems represent users and groups with a unique security identifier (SID), while UNIX operating systems represent users with user identifiers (UIDs) and group identifiers (GIDs).

Account mapping is the process of correlating the UNIX UIDs and GIDs to corresponding Windows user and group SIDs.
