Why don't you try doing a little bit of research before writing a document that is full of crap? Microsoft is only getting into the directory market and Novell has a near decade head start. You can install eDirectory on Linux, UNIX, Netware, Windows, etc., please tell me on what platforms AD will install? Windows only you say? That is a great solution for a mixed environment that is looking for an enterprise solution. NOT!

Do your research you putz.
