NAME

pcnfsd – (PC)NFS authentication request server

DESCRIPTION

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.

FILES

/etc/passwd: This file should be in the format used on many flavors of UNIX (SunOS 4.x and later, 4.4BSD, System V Release 4 and later, and others).

/etc/group: This file should be in the format used on many flavors of UNIX (SunOS 4.x and later, 4.4BSD, System V Release 4 and later, and others).

/etc/shadow: This file should be in the format used on many flavors of UNIX (SunOS 5.x and later, System V Release 4 and later, and others).

BUGS

When the call fails, pcnfsd doesn’t fake by setting the UID and the GID to acceptable values. Passwords that have been encrypted using Kerberos are not supported.
