Dear All,
First of all this is my first post on Jenkins so I hope I'll do it right

I installed jenkin V2.0 on my Server 2012 R2 STD however I can't seem to make it connect to internet.
I have a proxy that is using authentication to access internet, and all my servers are in AD.
When I do a network trace, I can see that Jenkins is sending the request to the proxy twice, however it sends anonymous request both times, so of course my proxy reply with error 407 (auth requested).

I checked the forum and other sites already but can't seems to find any answer.
I attache the screenshot of my configuration and the network trace in hope that you guys can help (either to fix the issue or tell me what I'm doing wrong hehe ).

Regards
Christophe
