Iím a bit confused as to how NetWare 6.5 is licensed. As far as I know it
is based on user objects not concurrent connections like NetWare 5.1 and
previous versions. Is this correct? If it is not correct let me know and
ignore the rest.

If it is correct can a NetWare 6.5 server be inserted into a NetWare 5.1
tree for something like a webserver, Zenworks or GroupWise (client server)
that only a few admins to connect to directly but the user population will
never connect to. If not would I have to create a separate tree for a
NetWare 6.5 server since we donít have the money to buy licenses?
