The existing Active Directory has been thoroughly setup with groups assigned to users as applicable. Among these groups there is a group "Economy" that has to have access to certain documents.

• Step 1: Create a group called "Economy" in zFTPServer.
• Step 2: Integrate this group with Windows by checking the "Integrate with Windows group".
• Step 3: Add resources as necessary, effectively making Windows-users logging in having access to all these files.
