Sharepoint 2007 and Access Manager 3.2

Hello,

I have an unconventional install of Sharepoint 2007...installed without an Active Directory Domain on a Windows 2003 R2 Standard Edition server. The users are defined on the Windows server, but I would like to authenticate to eDirectory. I was told this could be done using Access Manager, so I have installed version 3.2. And, this is where I'm stumped. Is there any documentation on how to set up Access Manager and Sharepoint? Can this even be done?

Any help would be greatly appreciated!
