Im having a few issues wrapping my head around how schemas should be implemented. If I do a default install of openldap (2.4.23) on CentOS 6 the following schemas are automatically included:
Throw away this installation and start over. You don't want to use 2.4.23, and you definitely don't want the CentOS build of OpenLDAP.
As for the schema question, there's really little cost to having the ldap server have them loaded. Whether you wish to keep them is up to you.
