Hi Rick<br>>> Thanks, I have created user (luser6) in client as

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.<br>><br>> You can check that this is configured correctly
by running on the MDS (as root):<br>><br>>
/usr/sbin/l_getidentity -d {uid}<br>><br>> to verify that "uid" is
accessible from /etc/passwd (or NIS/LDAP/AD/whatever).<br>><br>>

not mandatory. You just need a way to ensure that user accounts
are visible to the lustre servers. You could also use LDAP or even
just /etc/passwd. You?ll probably just want to choose
