Hello,
I don't have the articles handy, but Novell's e-directory is faster and more reliable for an Enterprise environment than Active Directory. e-directory, or NDS as it was called, has been around since the mid 1990's, and offers a lot of management options for the Enterprise. NDS can manage disk quotas across the enterprise; AD does it on a server by server basis. NDS, in my opinion, has better tools and greater stability and functionality.
AD is not a deadbeat product, however. AD is tied into MS Exchange for Address book information. AD is a well needed step from the NT4 days of server islands out there without Enterprise management. AD can easily be setup to work with WAN sites and their often slow connections.
Perhaps to help us out, you might wish to tell us a bit more about your company, and what your needs are. What is important to you? Email? Printing? Citrix support? Different name spaces on the file servers?
Also, in order to attract comment to this topic, I am breaking your question into a new thread, so that others may notice it, and generate comments.
And between you and me, I would take the Novell.
Christian
