I had to laugh when I got my latest e-mail from Centrify, in the Subject line was “See Microsoft's Demo of Linux Integration;” I worked with Centrify when I was on the Microsoft TechNet team for Active Directory Integration on Non-Microsoft platforms. Of course I opened it and was presented with a link to View “Keith Combs” Blog, which by the way, Keith has been one of Microsoft’s prolific bloggers over the past couple of years. I worked with Keith for 3 years while I was on the TechNet Team, he and I both had passion for talking about competitive platforms, but from a co-operative perspective.
Here is the link to his “BLAHG” and the 3 part screencast series he did on Interop between Windows Server 2008 and Linux / OS X - Windows Server 2008 Interop with Linux and OS X
Note he also has a link in the comments to download the 3 files as well for offline viewing capabilities.
