Hi
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?
Since I have 2 MGS/MDS and 2 OSSs.
Regards

U need to make ldap client on Lustre MDS & OSS that’s it. Make sure iptable must be disable or iptable allow ldap connectivity.
Set selinux disable too..

Hi
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?

For lustre user management it’s mandatory to have same UID / GID else you couldn’t able to sync directory properly.
You can setup NIS Server on ur master node for easy sync of user. NIS setup is easy too.
Thanks & Regards
