I was able to get iCal server running no problem as long as the
10.5 server has a trusted bind to the 10.4 ODM. However, users in
the 10.4 OD system can't be enabled for calendaring. When you
enable and save in WGM, and then refresh, it shows as not enabled.
I was looking around on a test 10.5 ODM and I didn't see any schema
changes. Has anyone been successful with this?
This question is way over my head, but it does resemble a discussion
I've seen elsewhere:
What you are seeing there is Augmented records (AKA The Cylinder of
Destiny) in action.
1. Setup in a workgroup config and bind to your older OD system. AD
works too.
2. Open Server Preferences and import the users and groups you want.
3. Now you can edit those users as if they existed on that server to
enable 10.5 services.
What is going on behind the curtain is that an augmented record has
been created for those users that just contains the 10.5 specific
schema additions. They really don't exist on the 10.5 server, but they
appear to. In the background DS is compositing the original account
with the arguments to create the total picture. You can take a look at
the augments with the inspector in WGM.
Augmented records are safe to use for all sorts of stuff as they can't
override the source of the info in the original DS. To the client it
feels like a schema mod, but you never modify the original records.
It works well for a 10.5 collaboration server as the server is all
that needs to look at the augments for things like the Wiki. iCal is a
bit harder as you will need to fill in the CalendarURI by hand as the
client won't see it for the auto-setup.
