definition of AUTH_UNIX

[Eric Wassenaar]

The rules for permission checking in NFS transactions are rather vaguely
described in the SUN documentation about NFS. It is stated that "the NFS
server is expected to perform AUTH_UNIX style of authentication checking".
As far as I can find out, this means that credentials like uid/gid, and
groups, are passed from the client to the server to be used in the
permission checking on the server host.  Or is there something more to it
? Specifically, does AUTH_UNIX require that the NFS server ensures the
existence of the client uid/gid in the /etc/passwd file on the server host
? (assume no yellow pages) Where can I find the proper definition of
AUTH_UNIX ?
