My Xserver environment and help for the purpose (Important)

"Then I would like to have all users use the iCalserver as needed. They can update their own calendars, publish to other users and read the project calendar which they have no permission to change."


You describe how the older iCal publish and subscribe work. For this you don't need iCal Server (CalDAV), only WebDAV (a shared web folder).

iCal server needs working DNS (forward and reverse records) because you need a working OD, OpenDirectory -> OD user accounts enabled for calendaring. Depending on other OS X Server services used you probably/might need DNS setup right anyway (sudo changeip -checkhostname should report no problems).

iCal server client machines doesn't need (but it helps) to be bound to the OD.

When using iCal server with iCal 3.x client you delegate read only or read and write priviledges to other iCal server users from within the iCal client iCal server account settings.

Other iCal server clients that have delegated access to their calendar to your account will show up automatically in yours. But you will need to add other users accounts manually to you account when you want delegate (r/rw) access to your calendar to them.

+"The Network team did mention I should not turn on DNS This would mess their network up?"+

Sadly this shows their ignorance rather than yours. I can't see how configuring DNS on the Server itself can interfere with anything? If you configured DHCP Services then yes they may have a point. What I think Leif means is for what you want there has to be working DNS available somewhere. It does not need to be on the Server itself. If the network environment already has an existing and mature DNS it makes sense to use it. As long as appropriate records are created for it is all that matters.
