I tried to set in the [users] share. The result in the log.smbd looks 
like this:

I think thats due to the fact, that the NFSv4 support is probably not 
build in the Linux ZFS version of proxmox. According to what I found on 
github, the support for NFSv4 ACL is still under development.

Any other ideas?
