I have setup a secured FTP (SFTP) using OpenSSH and my IIS. It works fine, I am able to loginto the root folder of my FTP. I am now trying to setup folders per user (one user can only one folder)and I have followed several tutorials for FTP User Isolation (http://woshub.com/ftp-site-with-user-isolation-on-windows-server-2012-r2/, https://blogs.iis.net/robert_mcmurray/FTP-User-Isolation-with-Multiple-User-Accounts), create the folders as requested (LocalUser and folders named after the user accounts), setup folder permissions accordingly, created virtual directories, isolate users.. When I try to log into WinSCP or FileZilla, each indivudal user can still access the whole folder structure.
What did I miss? Could it related to the fact that I am using SFTP instead of a regular FTP or FTPS?
