Shared Contacts in Snow Leopard Server’s Address Book Server

I'm playing with 10.6.1 Server and so far everything works great (mail, web, wiki, etc) except one thing: The Address Book Server. I've set up the server, turned on SSL, connected a client to the [temporary] domain and created a vCard that "syncs" correctly with the Address Book Server, but I'm having trouble understanding how the "Shared Contacts" (the Directory lookups) work. From what I've been able to gather, there is no such thing as "a shared address book" on Snow Leopard server; the vCard-based system is limited to serving Address Books on a per-user basis. I've seen discussion on Apple's discussion website about how you can create two accounts; one for your regular user and one that is supposed to store the "Shared" address book, but it feels very clunky. Apple's documentation on Address Book Server mentions how you can migrate your 10.5 LDAP based Shared contacts to the Address Book Server but while I haven't tried that I'm at loss as to how you're supposed to enter information into the newly migrated system. I can't find any knobs in neither the Address Book.app nor Workgroup Manager. Am I totally off in summarizing the Address Book server being totally unusable other than a pseudo-backup/syncing solution?
