na_pcnfsd - (PC)NFS authentication request server
pcnfsd provides a personal computer NFS client with the
authentication services. This release supports versions 1
and 2 of the PCNFSD protocol.
When pcnfsd receives an authentication request, it will
register the user by validating the user name and password
and returning the corresponding UID and primary GID pair,
and the secondary group set for PCNFSD version 2.
It will look up the user in the /etc/shadow file, or the
passwd.adjunct NIS map, if present, to find the user's
password. It will look up the user in the /etc/passwd
file, or the passwd.byname NIS map, to find the user's UID
and primary GID, and to find the user's password if there
is no /etc/shadow file or passwd.adjunct NIS map.
For a PCNFSD version 2 request, it will scan the
/etc/group file, or the group.byname NIS map, to find all
the groups of which the user is a member. It will look up
the user in the auto.home NIS map, if NIS is enabled, to
find the user's home directory; if NIS is not enabled, no
home directory will be returned.

UID and the GID to acceptable values. Passwords that have
been encrypted using Kerberos are not supported.
