With this extension enabled Windows users will automatically be able to logon to the FTP server without the need to add them to zFTP! - The users in zFTP will take precedence, so if a user exists in zFTP (and is not connected to a Windows account) then the zFTP account will be used for login. - If Authentication Integration for Windows is enabled, and a user tries to log in, access will be authenticated against the given Windows Domain (or Server). - Access to FTP can also be restricted based on certain Windows group memberships, so it will be very easy to administer which accounts that should be able to login through FTP using only Windows group management (e.g. in the AD)

Examples on how to use the virtual filesystem

  • Basic setup: The entire FTP structure is taken from the "C:\FTPRoot" folder on disk.



  • Managing web accounts: The following group account is created and by simply assigning membership to this group when creating new accounts the management of a huge amount of accounts becomes a breeze. In this example there is a total limit of 50 MiB storage for each user, but the folder "cgi-bin" can never go above 5 MiB.
    All the necessary folders are of course automatically created on the server once the user logs in, so there's no need to manually do anything else.



  • Merging several folders: The entire FTP structure is taken from the "C:\FTPRoot" folder and "D:\Resources\Public" on disks. These two folders get merged and look like one big disk to the user.



  • User specific folders: Every user gets their own home directory automatically in "C:\FTPRoot\[Username]", with full access rights.



  • Date specific folders: The folder with todays date will have full access rights (available for upload), while all others are only available for downloading.



  • User specific upload folders: Every user will get their own upload area with a limit of 50 MiB storage capacity, while still being able to download all files by other users.



  • Using several group memberships: Create a separate group for each available project (specifying in each case which files/folders that project needs) and let each user be a member of the projects needed (this makes it very easy to e.g. manage changes).
