web api windows authentication unauthorized on foxxl - asp.net-web-api

Question

I hope somebody can help me with the following issue, I have been working on a mvc4 web api running on .net 4.0 and ef code first. I am trying to use basic authentication in combination with the authorize attribute. It works on my Azure trial and also on Localhost but i cant get it to work on foxxl hosting and it keeps asking me for credentials which seem to be invalid when i try it on the foxxl hosting. For testing i am not using https so but this will be included in release version.
Here is some sample code that i have added for basic authentication:

EDIT
I also tryed adding the authentication lines to my web.config because my hosting said this would solve the issue. But when i do that and run it localhost it gives me the following error: This configuration section cannot be used at this path. This happens when the section is locked at a parent level. Locking is either by default (overrideModeDefault="Deny"), or set explicitly by a location tag with overrideMode="Deny" or the legacy allowOverride="false".

Answer 1

Look at your web.config.
<authentication mode="Windows" />
It is set to Windows Authentication. You will need to remove that line.
