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)

Usage Examples

Some features in zFTPServer Suite are very powerful and might need some explaining to highlight their full potential. Some examples of more advanced usage are presented here.

Events and Messages : Reactive (scripting examples)

The Reactive features basically lets the server react to events after they happen by executing batch scripts or to send custom messages.

An example would be to automatically scan uploaded files for viruses. The ability to execute external batch scripts also makes it possible to launch custom programs, scripts or to perform specific actions based on actual events.

Certificate management

zFTPServer can handle encrypted sessions for both users' regular connections and file transfers as well as for the administration interface. If you intend to use a certificate stored in Windows Certificate Personal Store it is important that you imported the certificate into Windows without enabling strong private key protection, otherwise you will be prompted with a Windows dialog every time zFTPServer is started.

Events and Messages : Proactive (scripting examples)

The Proactive features essentially lets the server react to events before they happen.

Following a request to e.g. login or upload a file the server can for instance verify login or upload operations against external databases or check whether the user is permitted to upload a file of that specific type. We can for instance enforce that a specific user only be able to upload .doc-files.

In combination with the Reactive module we can script more advanced business applications rules verifying a user login against a SAP database and subsequently when the user is allowed to login, run scripts that execute financial reporting in SAP, directly posted and available to the specific user on the fly (reports are then automatically removed after logout).

Scripting Examples

These scripts utilizes the administration protocol to manage the server from custom applications. This technique may be used to integrate zFTPServer Suite with custom systems, such as web applications or business systems.

The easiest way to explore the scripting API is to use a simple telnet application (included with Windows) and connect to the admin port (default 3145):

telnet localhost 3145
220 .
user admin
331 User name received, need password.
pass abc
230 User logged in, proceed.
