I am looking for documentation for setting up ZfD in a mixed environment. I
have an existing eDirectory Tree with Zen 6.5 installed. I need to implement
support for Active Directory based machines. I realize I will need a middle
tier but I do not know what if anything else will be required.

I am assuming some kind of user and workstation objects will be created on
the eDirectory side. If the middle tier is a 2003 server will I need
eDirectory for Windows?
