Note that the "luser6" needs to have the same numeric UID/GID as on the clients.
Copying /etc/passwd to the MDS is the easiest way to do this (it isn't needed on the OSS nodes).  You probably do NOT want to copy /etc/shadow to the MDS, to prevent regular users from logging in there.

You can check that this is configured correctly by running on the MDS (as root):

  /usr/sbin/l_getidentity -d {uid}

to verify that "uid" is accessible from /etc/passwd (or NIS/LDAP/AD/whatever).
