LDAP memberOf setup


Just wondering how you install the memberof overlay module in the OpenLDAP server when its installed through YaST? I know how to install it through the more conventional methods where there is a slapd.conf, but SuSE appears to keep all the LDAP configuration in ldif files in /etc/openldap/conf.d even the ppolicy overlay is somehow represented as an ldif in here.

Any help would be appreciated. Thanks
