Dbd::ldap is a dbi extension module adding an sql database interface to standard ldap databases to perl's database-independent database interface. you will need access to an existing ldap database or set up your own using an ldap server, ie. "openldap", see (http://www.openldap.org).

the main advantage of dbd::ldap is the ability to query ldap databases via standard sql queries in leu of cryptic ldap "filters". ldap is optimized for quick lookup of existing data, but dbd::ldap does support entry inserts, updates, and deletes with commit/rollback via the standard sql commands!
