Yes. I should have framed the issue more carefully: Are they as efficient as Windows' Active Directory and Group Policy? It's a bit of a hard-to-define question, and not many people have the experience to answer it.
I've seen plenty of deployment and configuration management tools that definitely fit the definition - those are easy to make - but were inefficient for one reason or another; that's the hard part.
One major advantage of AD/GP is the market power of being the tools for the dominant corporate OS: Every application vendor who hopes to put a toe in the corporate market makes their product work with AD/GP, including GPOs (Group Policy Objects) that provide the settings to manage their product, makes sure they work sufficiently well (at least they have incentive to try!), and supports them. If they don't, then corporate IT usually won't give them the time of day - it's a job requirement; their 'resume' goes in the circular file. Given Linux server share, I could imagine some good tools there.
A secret of IT management - the difference between what even highly skilled hackers do at home, and IT administration - is that the time resource is highly constrained; it's the most valuable asset and you spend it very carefully. You don't have nearly the time to do everything you need to do; you certainly aren't spending it trying to make some application work with your Linux config management for purposes of - what? your FOSS hard/wide-on? what is the big ROI here for this major project that you're going to bring to the VP? - and do it over and over again for each application. It's not even a consideration.
