we are planing to do account and password synchronisation between eDir and
AD in two steps:

edir Main-Tree <=> Identity Vault (edir IDM-Tree) <=> AD

I'm in the process of reading the documentation and trying to understand the
concepts and details. Now there is a statement in the documentation that
irritates me:

Bidirectional eDir Guide says that this driver uses LDAP and it says: "The
LDAP driver doesn't support universal password synchronization on the
Publisher channel."

Does this statement refer to the "Driver for Bidirectional eDirectory" or to
the "Driver for LDAP"?

In other words: since I need password synchronisation - can I user the
bidirectional eDirectory Driver? Or do I need the traditional eDirectory
