The LDAP server <link xlink:href="http://www.openldap.org/">OpenLDAP</link> will be used in the examples in this document; while the principles here should be generally applicable to many different servers, most of the concrete administration is <application>OpenLDAP</application>-specific. There are several server versions in ports, for example <package>net/openldap24-server</package>. Client servers will need the corresponding <package>net/openldap24-client</package> libraries.
