translucent overlay add an attribute to all users in a OU and subtree

Hi, (sorry for poor english)

I already ask here for meta and it's working (only have the date format conversion problem but we are about to find alternative)

So the ldap proxy can search for a user and provide attributes from an AD, Edir and openldap.

but now I want to add attributes to the edir and openldap users search result to have as much as from a AD user (example homeDrive)

I plan to use translucent to add these attributes, find that translucent cannot be used with meta so create new slapd instance.

I have add base and OU into this instance

I read carefully http://www.openldap.org/doc/admin24/overlays.html , and man slapo-translucent

I understand that they explain how to add attributes to only one group

here my questions

how can I add attributes to the translucent instance to all users in an OU (and sub) ?

is there another way to do what I want to do ?

thanks all for responses
