Tom Adelstein has written an article for Linux Journal on Samba and Linux in a Microsoft environment.

The piece begins with an analysis of benchmark results on Samba 3 performance (tests were done by IT Week), but then moves into an overview of Samba3 features. For more, read the full article, Linux in Government: Another Look at Linux in the MS Infrastructure.
