With Integrated Authencation, the web server *never* has the user's
password, so it can't authenticate to the remote machine on the user's
behalf. When you use Basic authentication, then the user's username and
password are both sent in clear-text to the webserver, so it can then
"impersonate" the user account to the remote file server, allowing you to
manipulate resources remote to the webserver.

For this reason, it is recommended to use SSL in combination with Basic
