Doesn't play well with others

After investigating a user report on the unability to map the blogs media folder, I have found these interesting facts:

1. Web Folders needs the whole path, from the server root up (/), to be WebDAV-enabled, even if I just want to map a specific path. This breaks, as blogentis maps the WebDAV folders deeper into the tree, and the path segments leading to these folders produce redirects to HTML pages.
2. For some reason, while it requests authorization, the HTTP headers of the response have an empty password set.

Standards are good, you have so many to choose from (and apparently get them wrong)...
