I have dabbled a bit with Linux and BSD based systems over the years both at work and home. This has primarily been around Apache, MySQL and PHP but has included struggles getting Samba connected to Active Directory. Recently I stumbled across this product from Centrify and thought it interesting enough to include here. I only wish I had found it a few years ago. When I get some time I will have a more detailed look at it.
