If this is possible, does the configuration allow one to define the overlay at the “backend” level, so that it applies to all databases of the same type? e.g. backend ldap overlay rwm rwm-rewriteEngine on
No. No modules in OpenLDAP have ever implemented anything for the "backend" keyword, it is purely a no-op.
Also No: overlays may only be configured on databases. Not backends.
