Re: [Samba] using Windows AD unwanted Group rights get applied to new Files

I used the expression 'regular user' because I wanted to make it clear that this user does not have any administrative rights whatsoever.

The 'primary group' had been set a long time ago, when the system was created. It had been set with ADUC, under the "Member of" tab, as told before.

Yes, of course. That's not the point.

It is also the behavior intended by the OP. Shouldn't a folder inherit the permissions of its parent when inheritance is on? If so, why does the group "Domain users" appear there with "Full control" permissions when it is not present in the parent folder?

Yes, I know, but one of your previous posts seems to imply that the behavior the OP wants is not possible unless you use the AD backend or a convoluted workaround. You also stated that changing the "primary group" would be ignored, which isn't. I thought it would be helpful to actually test it... I found the problem the OP complained about somewhat strange because I had never met it, and I had never met it because all my users had their primary group set to the intended group from the beginning, some years ago.
