I have no idea. What client(s) are you using?

All I can tell you is that the FreeBSD NFSv4.1/4.2 server does not
support the "dacl" attribute, because it requires that a flag called
na41_flag be stored for each file object and that is not currently
done in FreeBSD. (This is related to "automatic inheritance",
in case that is what you are referring to?)

Final comment. I am not aware of any recent changes in
this area, so if those settings were needed for your environment
in the past, the probably still are.
(see "man zfsprops" for the meaning of the settings)
