I am currently tasked with implementing Desktop Management 7 with SP1 on
an OES 1 (clean, Linux) server. I need some advise please.

Users currently authenticate to another tree (a server running OES 1
[linux]) with Novell client, so in my setup do I need the middle tier?
Also, if users still authenticate to that tree, do I need to specify that
in my setup which will in turn add lots of objects to my live tree? Or, as
a preferred method, I would like to run 2 tree and have one for
authentication and one for Zenworks, is that possible?

Thanks in advance
