Being based on 4.10.x or 4.15.x will not make a difference, they are
both, like all versions of Samba 4.x.x (so far), based on the functional

Well yes, but all the documentation I can find for a synology NAS says
it is based on DSM.
I cannot really say much more about synology, I do not own one, I have
never owned one and after this debacle, I am highly unlikely to ever buy
one, why would I shoot myself in the foot (note, these are my opinions
and yours may differ).
