I have to install an LDAP proxy on a compute cluster frontend. The idea is to avoid the compute nodes to make too many requests on the campus LDAP server.

How can I install this to make it work with the school's LDAP? The frontend OS is a RHEL 6.2. I found that I have to install the LDAP server and configure it as a proxy. But all I can find is examples of /etc/openldap/slapd.conf file configuration but after testing different configuration, no results. Furthermore, according to RHEL 6 - Deployment Guide, this config file is obsolete:

OpenLDAP no longer reads its configuration from the /etc/openldap/slapd.conf file. Instead, it uses a configuration database located in the /etc/openldap/slapd.d/ directory.

Any help is welcomed. Thank you
