Foreman installation behind a NTLM Proxy


I'm trying to install Foreman behind a NTLM proxy on a Ubuntu 14.04 LTS

Apprently, Foreman can't download some modules. Is there a file to
configurate to pass through the proxy. (like /etc/wgetrc)

I'm using NTLMAPS for the direct "apt-get update" which is working well.

Thanx for your answer.
