Home share directories are dropping group:domain-admin permission

Hi guys,

I din’t find this problem in the forum.

I use the “Use as Home Share” option for sharing home directories on TrueNAS-13.0-U6.7. As I need to copy existing user files and directories I’ve added an ACL for group:domain-admin. I only know the way to use robocopy under Windows to really copy all the permissions correctly and wouln’t know how to copy the user files under Un*x.
When I create the share all is working as expected, but the next day this group is dropped. It may be a Group Policy thing, but is there any way to prevent this?

When I created the share I had to manually add the group:domain-user the the domain directory:
setfacl -n -a 2 g:\domain-user:rwxpDdaARWcCos:fd----I:allow
If I don’t do that users don’t have a permission to login. How could I correctly create the share?

Additionally in the Share directory there are computer accounts created. Can I also prevent this?

I’d be glad if you could help me with any of the problems.
