Hi, After copying users details from lustre client /etc/passwd to lustre MDS server, it's working fine.
Now, I have bright cluster manager in my headnode, which has LDAP server. How do I configure my lustre servers to use that LDAP server?

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).

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 systems. > > For the purposes of testing, you could always just create the luser1 locally on each lustre server to see if things start to work. > > -- > Rick Mohr > Senior HPC System Administrator > National Institute for Computational Sciences > http://www.nics.tennessee.edu > > > _______________________________________________ > lustre-discuss mailing list > lustre-discuss@lists.lustre.org > http://lists.lustre.org/listinfo.cgi/lustre-discuss-lustre.org Cheers, Andreas -- Andreas Dilger Lustre Principal Architect Intel Corporation
