Hmmm. Yes, if you were in Windows Explorer, and looked at the properties of the file/directory and went to the security tab - that would view/adjust the NTFS permissions. However, it's not so obvious to me that we're changing the NTFS permissions on a AD object. [Perhaps we are, it's just not at all obvious that's what's going on.]

Yes, that's correct.
I've not found any way in FreeNAS to do it through the normal UI [where the configuration will be handled the way FN expects] and not use a "Windows" based approach. [i.e. There's no documented way to join FN to a Samba domain that's in the official docs. Since it's standard Samba, I'm sure it's possible at the CLI. But what issues will we run into when FN is configured "on the side" and not through the UI? I am not sure - but wanted to avoid complications by doing it in the most standard way via the options in the UI. I wanted to avoid such drama, if possible.]
I've found a few threads doing so via the CLI as a standard Samba join.
Perhaps going that route is more fruitful - I dunno.
All that said - if this IS a permissions issue, how come we don't see something in the logs that looks like a denial/error/warning flagging permissions when we try to view that tab. Or why doesn't Samba return a failure to RSAT and we get an error at the RSAT console?
