So I installed Unraid 2 days ago (version 6.10.3 2022-06-14) and lifted it into our Windows domain.
AD initial owner: Administrators_xyz
AD initial group: Administrators_xyz
I can access the share with users from this group. Even if "everyone" has no rights.
I have created a group using the path described in the link.

Then I assigned a test user to the ReadWrite group.
Result: No authorisation. The domain server wnter "Effective Access" says that the user has full rights.
If I add Full Access under Permissions for Everyone, the user immediately gets access to the share.
Apparently the manually added groups do not work.
Yes, I have re-registered the user after he has been assigned the groups.
