Here's the scenario. We have outside consultants that get AD usernames and passwords to our network. Our web server (Win 2003) hosts multiple web sites that we would like to give out FTP access to the various people that need to update their files. We work in a mixed environment (Mac / Linux / Windows) and need to provide a client to streamline the instructions that we give out to everyone on how to update their websites. Ideally this would be a thin client that the end user would download through their browsers. We would like to be able to assign AD users to the folder that their website resides in.
Is there any FTP server solutions out there that provide FTPS (we don't need full encryption, just the authentication handshake) and a client so that the user experience is the same accross the board for Windows servers and provide the user assignment to folders?
