Abstract:

This document proposes a convention to allow Windows NT users to be
represented on POSIX-based systems and Unix users to be represented on
NT-based and compatible systems, such as Windows NT 3.5, 4.0, 5.0, and
Samba.  The convention has relevance to POSIX-based Windows NT compatible
systems such as Samba, in order to allow such systems to interoperate
in a diverse Windows NT Domain environment, even though POSIX systems
currently have neither native support for the Windows NT Security model
nor support for the concept of remote POSIX users.
