<DIV>Hi</DIV>
<DIV> </DIV>
<DIV>I have successfully configured LDAP client on MGS server and it is working
fine. Do I need to configure all Lustre servers as LDAP clients?</DIV>
<DIV>Since I have 2 MGS/MDS and 2 OSSs.</DIV>

Hi Rick<BR>>> Thanks, I have created user (luser6) in client as
well as in lustre servers. But I get the same error as<BR>>> No
directory /home/luser6<BR>>> Logging in with
home="/".<BR>>><BR>>> But now I can cd /home/luser6 manually
and create files or folders.<BR>><BR>> 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>>

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
whatever mechanism is used on your other
