Yes. You've got a bright crystal ball, btw. 
Since a longer time I deeply regret having gone to Stretch testing. 
Two month ago I did compile samba-4.5.0 without any problem, but 
apparently Debian testing did break something deep inside the system. 
I already migrated some of my boxes to Gentoo, but that is a long and 
painful way, too. :-( 

Thank You anyway
Peter
