Problems with slapo-rwm

Hi

I am trying to get slapo-rwm module working in a cn=config setup

I have openldap with a local DB and ldap database backing onto a MS AD DB

I am trying to rewrite objectclass group to groupOfUniqueNames and attribute member to uniqueMember

this is what i use to set it up

dn: cn=module{0},cn=config changetype: modify add: olcModuleLoad olcModuleLoad: {4}rwm

dn: olcOverlay=rwm,olcDatabase={1}ldap,cn=config changetype: add objectClass: olcOverlayConfig objectClass: olcRwmConfig olcOverlay: rwm olcRwmRewrite: rwm-rewriteEngine "on" olcRwmMap: {1}objectclass group groupOfUniqueNames olcRwmMap: {2}attribute member uniqueMember olcRwmNormalizeMapped: FALSE

but when i try a ldapsearch it doesn't work , the object class and attribute are not re written
