Network context does not work when no-admin

[Paul Peereboom]

Since rally 0.10 it is possible to run a task without admin credentials(awesome!). I'm trying to get this to work for some tasks but i cannot specify a network in the context since it is prompting for admin credentials:

rally --version
0.10.1~dev5

deployment config (no admin specified):
(installation) root@rally-server:~# rally deployment config 4edf805c-a7a4-4af6-b5e2-98abbfef0e5a
{
    "openstack": {
        "auth_url": "https://example.com:5000/v3",
        "endpoint_type": "public",
        "region_name": "RegionOne",
        "users": [
            {
                "password": "Password123!",
                "project_domain_name": "Default",
                "project_name": "rally2",
                "user_domain_name": "Default",
                "username": "rally"
            },
            {
                "password": "Password321!",
                "project_domain_name": "Default",
                "project_name": "rally2",
                "user_domain_name": "Default",
                "username": "rally2"
            }
        ]
    }
}

Reason(s):
 No admin credential for openstack`

Am I'm doing something wrong or how should I fix this?

Sorry, admin is required in network context.

Ah, I see. Not sure why tough, now you cannot specify a network_id or empty network to spawn instances in.
