Configuring OpenLDAP server on CentoS 6
Introduction
LDAP (Lightweight Directory Access Protocol) is commonly used for managing users and groups for authentication purposes, or for system configuration information. It can also serve as a virtual phone directory and address book, allowing users to access information about other users in the directory.
CentoS 6.2 ships with OpenLDAP 2.4.23 which contains the cn=config Directory Information Tree (DIT) that is used to dynamically configure the slapd daemon. This allows modification of schema definitions, indexes, ACLs, etc without stopping the service.
The goal in this post is to configure OpenLDAP so that it can be used for user authentication. For simplicity, the Samba file sharing configuration and user migration will be handled in separate posts.
