Linux

Yes, joining AD is trivial. But you're going to have to configure PAM to use it for authentication yourself, which is non-trivial. Nor are you going to benefit from group policy, including automatic cert policy if your org uses it.

If you don't have a dedicated Linux team at work, I wouldn't bother. You can use it, but you'll be doing a whole bunch of integration work too. (Or, obviously, just use Linux, do the minimum to comply with policy, then provide creds as necessary to access network resources.)
