SFTP Connector issue

Question

I have a couple of questions about the SFTP connector:
Firstly I have been trying to get the SFTP connector to work but so far have had no luck. Having set up the connector and set all the package settings all of my requests fail with an HTTP 400 response -
"User Name Value cannot be null, empty, or cannot contain only white-space characters.".
Where/How do I set the username property? Its not one of the of the package settings, and its not passed in via the API calls (according to swagger).
My second question relates to the "Accept any SSH Server Hostkey" package setting. Can you confirm that with this set to true that it setting the server key is not required?

Answer 1

Documentation has been updated since my original post that describes how to specify username/password, or username/private key. (http://azure.microsoft.com/en-gb/documentation/articles/app-service-logic-connector-sftp/)
Connections however are still failing after security has been correctly defined with:
2015-04-16T03:40:05 PID[39436] Error **Exception thrown: WinSCP.SessionRemoteException, Network error: Connection to "sftp.server.com" timed out., at WinSCP.SessionLogReader.Read(LogReadFlags flags)

So it still looks like there is some sort of error going on here.
