This is the first time I've played with IIS and FTP. We have around 2000 users in AD. Each of these users has a share on the network, all under a root folder, labeled with their username.

Ex:

\\network\john.doe  

\\network\jane.doe

I'm trying to setup an ftp server in IIS 7 to allow users access to their directory and only their directory. Kind of like a web host, where I sign up for an account, login with ftp and get directed to my own folder. The only difference here is that we don't have to create directories, they already exist.

Here's what I've got:  

 - ftp site in iis that points to the root directory "network" that contains all the user directories  

 - basic authentication and filled in the domain  

 - authorization (all users) for testing purposes  

 - ftp user isolation -- username directory checked

Now I understand the last option is NOT what I want because it allows the user to move up to the root. However, this is the only option that allows me to login successfully and directs me to my folder. If I select either of the isolate users options (disable global or enable global) I cannot login. No message, just the authentication prompt keeps reappearing.

What am I missing here?
