Hello,
I have a few ldap clients which were set up by my previous sys-admin.
1. In some of the servers I see that the configuration is done in /etc/pam_ldap.conf, /etc/nslcd.conf and there is a nslcd process running on the clients.
2. On other servers I find that there is only an /etc/ldap.conf and there are no nslcd process running.
