Permissions only for assigned subfolders

[lissa091]

What is the best way to deal with the following problem?

We have a parent folder and several subfolders. There is an Admin user who has access to all folders. And several users who only have access to the subfolder they are assigned to.

We use S3 as storage.

At the moment, as a normal user, I can switch to any other subfolder after SFTP access. How do I set the permissions correctly so that this is no longer possible?

The following instructions have not resulted in any change:

Hope you can help me.

Thank you.
