As far as I recall, what you need is not possible.  You can:

Because the OP wants to have anonymous access for some clients of the proxy

Again, AD can be configured to allow anonymous binds, but AFAIK as of Windows

financial auditing companies in their IT auditing) mandate that it not be

handle this scenario, though.

IMHO, it would make sense to support this mode of operation.

Sorry but that just doesn't compute. If you have organizational security standards that are being audited and they forbid anonymous access, then allowing anonymous access to an OpenLDAP proxy that connects to AD is going to be equally forbidden.

Come back with an argument that actually makes sense from a security perspective first. Otherwise this is just creating back doors to do end-runs around your sysadmins and company policies.
