I realise the documentation for slapo-memberof indicate that this isn't possible, but I thought it worthwhile asking here anyway — is it possible to use the memberOf overlay with groups that use memberUid as their membership attributes, rather than user DNs?

We have a large existing LDAP database that has thousands of groups like this, and would very much like to use slapo-memberof.

Any pointers (positive or negative) much appreciated — just so I know for definite.
