</div>Note that the "luser6" needs to have the same numeric UID/GID as on the clients.<br>
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>

> NIS is 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\u2019ll probably just want to choose whatever mechanism is used on your other systems.<br>
