maas myuser node-groups import-boot-images

Hi,

After a fresh install of maas on ubuntu 14.04, I can't find my way to import boot images behind a squid with auth.

maas myuser maas set-config name=http_proxy value=http://myname:mypass@192.45.0.2:3128
{"http_proxy": ["Enter a valid URL."]}

do not work whereas :

maas myuser maas set-config name=http_proxy value=http://192.45.0.2:3128
OK

Worked, so how can I provide infos about my user/password for squid authentification ?

I also tried this :

sudo http_proxy=http://myuser:mypassword@192.45.0.6:3128 maas myuser node-groups import-boot-images && tail -f /var/log/maas/celery.log
