Sharepoint : AD to eDirectory move? Help.

First, let me say : I am not familiar with Novell.

We currently have Sharepoint farm servers and SQL server, located in a Windows Domain.

We have tools (Sharepoint web parts) allowing calendars, mails, address books... to be shared between GroupWise and our Sharepoint. So our clients can see their info from the Sharepoint portal.

Is it possible to integrate (or migrate) our Sharepoint servers into Novell? If yes, how to do it? Keeping in mind that those servers are, at the moment, part of a Microsoft Domain.

Thank you very much!
