One of the problems with Windows XP is that when working with non-Windows servers and services that it supplies the wrong login authentication information. When you are prompted to login to a system like WebDAV, Windows XP wants to send DOMAINUser or user@domain.com – neither of which are particularly useful if you want to connect to a service that doesn’t expect a login in this format. There’s no easy way to get round this, and that can mean that supporting Windows XP WebDAV clients on your Apache server can be impossible.Fortunately, the folks at LuluWARE have an answer. Their Apache 2.0 authorization module will reformat Windows XP style logins into the bare format required by the Basic authentication system used in Apache for authentication.You can download the fix from here.Thanks to Chuck Gentry for this little piece of useful information.
