Domain Authentication on DMZ FTP Server

We have a Microsoft FTP server (non-domain computer) in a DMZ (behind a PIX) utilizing local accounts for FTP authentication.

My boss would like to use a combination of local accounts and domain accounts for authentication, so that domain users on domain computers would have single-sign on.

I would like to do this while minimizing security issues.  Do not want to open domain to the outside, do not want to join the FTP server to the domain.

Looking for ideas.

hard to eat your cake and have it too.

You could try certificate authentication, or setting up a good sftp.

you are going to have security concerns with whatever solution you implement as somebody inside your network could obtain your usernames and passwords for the server exchange and then use it to get into the ftp server and do damage.

(just a simple packet sniffer would allow someone on the inside to gain access to the passwords.)
