When performing webdav (http/ssl) connection when path is defined as username the abs_path requested error is displayed. The server address is
myserver.com, username is foo and path is foo
Now the URL filed in Open Connection window is displayed as follows
https://foo@myserver.com:443/foo
upon connection abs_path error is given - please note that the above url is valid and opens up fine in the browser
now when path is changed to /foo connection is successful, but URL is still the same
