As this week I also looked into the functional levels that samba 
supports, I must say that this wiki page:
https://wiki.samba.org/index.php/Raising_the_Functional_Levels
looks as if samba 4.4 and later support 2012_R2.

I understand that this is not the case, but I feel that the info on the 
wiki is (at least) confusing. (or even plain wrong)
