Digest WebDAV realms not accessable to Windows clients

IE on Windows cannot authenticate to a secure WebDAV realm when the realm is configured to use Digest authentication. Basic authentication has always worked for us in the past, but clear-text passwords are a concern. Further, we've discovered that the newest version of Dreamweaver (CS3) cannot connect to a Basic secured realm, but can connect to a Digest secured realm. Can I tweak Apple's WebDAV module to honor Digest requests from Windows clients? IIS WebDAV module supposedly presents the same dilemma to Windows clients, but there are IIS tweaks to make it work: http://www.webdavsystem.com/server/documentation/authentication
