The openldap server and the clients were installed following the instructions here.

On the client, the configuration follows this.

I am just able to follow the configuration steps. But I don't quite understand how NSS and PAM work. Could anybody point me the right direction on how to figure out who and when login on the client servers with authentication using a central openldap server?
Hi, I using openldap to manage users of a number of ubnutu servers. But I don't find a way to give users root permission on these servers? Could anybody show me how to do this with openldap? Thanks.
You're not telling us which PAM/NSS software you're using. Some software (e.g. sssd) ignores LDAP user entries with uidNumber 0 for very good reasons.
But this is rather off-topic here.
