Have you tried the 'net rpc vampire' approach? I have not and do not know if 
it works. My question is shot from the hip.

The other possiblility is to do an LDAP dump of the ADS directory, then rework 
the data into a valid OpenLDAP LDIF file. That is a method that does work, at 
least for getting the directory contents.
