Comment 4 for bug 778395

I am having a similar issue. I'm guessing my corporate net proxy is causing the issue. The proxy requires authentication and I am not getting a prompt from Ubuntu One when it tries to make the connection.

I have configured the proxy client and it works for most things but it usually prompts for authentication even though I have supplied the information in the"Details" option. I run into similar issues with many apps the try to connect to the network. Even with the authentication information supplied the apps seem to ignore them making the proxy option nearly useless.

I wish there was an option for it to pass my username and password from logging into the computer as we utilise single sign-on anyway.
