Uncomment the above two lines you need them ;-)

Have you actually given your users and groups a uidNumber or gidNumber
attribute inside the range 3000000-4000000 ?

If not, change the backend to 'rid' instead of 'ad' and remove the
schema_mode line.

The Same goes for the above line, if you have no gidNumber attributes,
remove it.

uncomment the template lines if you use the 'rid' backend

Add 'vfs objects = acl_xattr' as well
