I just moved a Filemaker Server from 10.6.8 Server to Windows Server 2012 and I am trying to get external authentication to work with my Open Directory running on 10.8.5 with Server 2. On the old Filemaker server all I had to do was join the 10.8.5 OD server and external authentication would work. cannot figure out how to get Windows Servers to pass the Filemaker External authentication request to Open Directory. I have installed pGina on the Windows Server and when I test it in pGina it authenticates but when I try to connect via Filemaker the account still doesn't authenticate. I’m banging my head trying to figure this out or if it is even possible.
