Roles in OpenLDAP with back-sql

Hi everyone,

Is anybody know if it's possible to define roles in OpenLDAP using back-sql?

Here's the thing, we need to prevent some of our users to see "everything". We need to filter results for some groups of users. But we need these rules in the database (Postgres) to be able to change them dynamically.

Problem is that, currently, when a user send a search query, OpenLDAP does not include in any way the DN of the user who made the query. As a result we have trouble creating scopes by user/group.

Thanks
