Comment 18 for bug 504423

if your willing to test it:

- locate duplicity/backends/ftpsbackend.py of your duplcity installation
- open with editor
- locate line ca. 83

os.write(self.tempfile, "user %s %s\n" % (self.parsed_url.username, self.password))

- edit and add one line in front of it and indent the original line by 4 spaces

if self.parsed_url.username:
    os.write(self.tempfile, "user %s %s\n" % (self.parsed_url.username, self.password))

does it work?.. ede/duply.net
