Forbid removal of Windows folders

[svenny]

I'm using TrueNAS Core ( version 13.0-U5.3 ) connected to a Windows AD server. The system is working very well. My issue is that I can't prevent deletion of Windows user profile folders: when a new profile is created Windows creates some folder for the new user (for example "Documents" or "Downloads" etc.): I would like to forbid removal of these folders.

I tried to follow the advice given in this thread:

How to set the user not allow to delete a file or folder in FreeNAS

but without success.

I've also tried with chattr command but this is not supported:

Code:

chattr +i Desktop
chattr: Operation not supported while setting flags on Desktop

Is there a way to resolve this issue?

Many thanks in advance.

Cheers.

I also tried with chflags command:

Code:

chflags uchg Desktop
chflags: Desktop: Operation not supported

Same result as with chattr.

Cheers.

It seems that ZFS on FreeBSD only supports the use of schg as indicated by the following thread:

Unable to chflags on ZFS filesystem

So I tried the following command:

Code:

 chflags uchg Desktop

The uchg flag has been set correcty:

Code:

ls -lo Desktop
drwxrwxrwx+ 3 DOMAIN\user  DOMAIN\domain admins  schg,uarch   5 Dec 11 16:45 Desktop

But the Desktop folder is still removable by the Windows user...

Cheers.
