Permissions seen as "rwx------" from Mac despite ACLs having Full Access for group

[EMP-Tea]

Show : TrueNAS Mini XL+ System Details

OS Version:
TrueNAS-13.0-U1.1 (Core)

Model:
TRUENAS-MINI-3.0-XL+

Memory:
32 GiB

8 bays filled with 4TB drives
Single ZFS pool in RAIDZ2
500GB SSD for mirrored boot pool

I set up a test user and dataset, shared using SMB and mounted in MacOS Mojave.
The dataset was created with the following permissions (whatever the default is when the dataset is created):

Show : ACL for test user's dataset

In the Mac terminal, I can cd into the volume and create a file.

Code:

Users-Mac-Pro:~ macuser$ cd /Volumes/Test/
Users-Mac-Pro:Test macuser$ touch test.txt

From the Shell on the TrueNAS GUI I can cd into the Test directory. When I check the file permissions, it looks like this:

Code:

root@truenas[~]# cd /mnt/tank/Test
root@truenas[/mnt/tank/Test]# ls -l test.txt
-rwxrwx---+ 1 testuser  testuser  0 Aug  8 17:02 test.txt

But back in the MacOS Terminal, when I check the permissions, the output looks like this:

Code:

Users-Mac-Pro:Test macuser$ ls -l test.txt 
-rwx------  1 macuser  staff  0 Aug  8 17:02 test.txt

Is this normal? Shouldn't the permissions look mostly similar? Is there something I'm not understanding? Is it because one is the root user and the other is not? Is it a bug in SMB?

Nope. Not a bug. That's just how MacOS chooses to interpret the NT security descriptor. You would see the same if you connected to a Windows server.
