Re: management
When a government makes a strategic decision to commit to Linux (or BSD or anything else that isn't Windows) anyone coming along whining that there isn't AD (or substitute anything else MS specific) is going to be told fairly brusquely to stop bringing problems and come back with solutions.
The old orthodoxy will have become the new heterodoxy and those who fail to grasp that quickly will find their careers are in decline. It won't be product X being incompatible with the MS product, it will be the MS product incompatible with product X and that makes it the MS product's problem.
