I took a look at Methods For Fine-Tuning Samba Permissions, but it is really much deeper than I think I need. I think a sticky with a handful of common scenarios and how to setup your permissions would be extremely helpful.
See signature for setup. I can currently access several SMB shares from a Windows 10 machine right now. I have some trouble accessing them from Mac, but let's start with Windows for now. I can access all of the files, and I can write new files to the directories I have, but I can't edit existing files. I suspect this is because I created them with some other permissions and there is ACL stuff in there.
What I would like is to have a Dataset that I can expose via SMB and NFS. I would like to be able to authenticate to it using a user who I have already configured on FreeNAS. This user is a member of groups that own the directories/files in the Dataset. Further, how can I reset the permissions/ownership/acls of the files in that Dataset?

Mounting NFS on a Mac Client. Use this procedure to mount to the cluster manually from the command line: Open a terminal. For example, you can click on Launchpad Open terminal. At the command line, enter the following command to become the root user: sudo bash. You can also use NFS v3 to access gluster volumes. Extensive testing has been done on GNU/Linux clients and NFS implementation in other operating system, such as FreeBSD, and Mac OS X, as well as Windows 7 (Professional and Up) and Windows Server 2003. Other NFS client implementations may work with gluster NFS server.
To mount a QNAP Turbo Station NFS share from OS X, follow these steps:
- Start Finder, and go to Applications / Utilities / Disk Utility.
- Select File / NFS Mounts... from the menu bar.
- Click the '+' icon at the bottom left of the NFS Mounts window.

- Enter your Turbo Station's NFS URL, following the format of the example in the dialog.
- Under the URL, enter the mount location. A convenient place is under /Volumes. For instance, if you entered the URL as nfs://myserver/Public, enter /Volumes/Public as the mount location. Note: Don't create the subdirectory; it will be created dynamically when the share is mounted.
- Click the arrow in front of 'Advanced Mount Parameters'. A new text entry box is displayed. Enter:
resvport
.
- Click 'Verify' at the bottom right. Note: This only checks that your Turbo Station has NFS enabled; it doesn't check if the remote NFS URL is correct.
- A popup window should appear, saying 'The NFS server appears to be functional'. Click 'OK'.
- Click 'Save' at the bottom right of the NFS Mounts Window.
- Enter your password to allow Disk Utility to make the changes.
- This completes the process. Your NFS share should appear at the mount location you entered above.
I've already tried to tune the NFS connection on the Mac by editing /etc/nfs.conf. Nfs.client.allowasync = 1 nfs.client.nfsiodthreadmax = 128 With these settings I'm at least up from previously 15MB/s to now 25MB/s. However, this is still sooo far away from what I get on the linux boxes. NFS (Network File System) is the industry standard for file sharing on UNIX systems like Mac OS X. Each Mac OS X system can be setup as an NFS server to offer files to the network, or as an NFS client to access files shared by other computers. Different from other file sharing protocols built into Mac OS X, NFS has no limitations.
Since Mac OS X 10.8 (Mountain Lion) doesn't offer anymore to mount NFS shares from Disk Utility, manual mount is the only solution under that version.
Here is a Terminal command that permits to mount NFS share without problems, as some arguments are mandatory to make the mout fully MacOS compliant:

sudo mount -o rw,bg,hard,resvport,intr,noac,nfc,tcp myserver:/sharedirectory /Volumes/sharedirectory/
enter your machine admin password, and voilà.

- list of major options used:
- rw for read and write permission
- resvport (explanation in discussion)
- nfc permits to your finder to handle the UTF-8 NFC coding of Linux and Windows instead of Apple UTF-8 NFD (well explained on G**gle), if not used any file or directory named with accents maybe unseen by the finder (where still okay under a terminal session !)

By default, Mac OS X connects to an NFS server from a 'non-privileged' TCP/IP port, that is, ≥ 1024. However, the Turbo Station only accepts connections from a 'privileged' TCP/IP port, ≤ 1023. The 'resvport' option in the setup causes Mac OS X to use a privileged port.
If you don't specify the 'resvport' option, you will be unable to connect to the Turbo Station. If you use a Terminal CLI, and issue
ls /Volumes/Public
, for instance, the HDD and LAN lights on the Turbo Station will blink, and the Mac will display the error message 'Operation not permitted'. Many online documents refer to the '-P' mount option, but according to the mount_nfs(8)man page, this is 'highly discouraged'. The 'resvport' option should be used instead.
It's unclear why the Turbo Station only accepts connections from 'privileged' ports. In past decades, this was considered to be a security feature, as only the administrator of a shared computer could allow connections from such ports. Nowadays, in a domestic or SME environment, each user of a computer is their own administrator.
