Hi guys, I'm trying to access to Nova using a REST client but everytime I got an "Authentication Required" response. My goal will be to access, foreach vServer, to its diagnostics info, but now I'm stucked far away from that. I'm using DevStack but I also tried with an another OpenStack manually installed.

My REST requests are (in order):

Method: POST, Url: http://172.16.0.1:5000/v2.0/tokens, Body: admin:password or demo:password

And i got a valid token.

Method: GET, Url: http://172.16.0.1:5000/v2.0/tenants, Header: X-Auth-Token:{token got previously}

And I got a list of tenants for that token; if I have understood right these tenants are the ones that I can handle with my token. Probably the are others but Keystone lists and gives me access only for the ones of which I have authority.

Method: GET, Url: http://172.16.0.1:8774/v2/{one_of_the_tenant_id_got_previously}/servers, Header: X-Auth-Token:{token got previously}

I'll expect to be able to get the lists of the servers but I'm not... When I try I got a response with this headers:

Status Code: 401 Unauthorized
Connection: keep-alive
Content-Length: 23
Content-Type: text/plain
Date: Mon, 16 Sep 2013 16:15:36 GMT
WWW-Authenticate: Keystone uri='http://172.16.0.1:35357'

And this body: Authentication required

I also tried to make the rest call with the command "cURL" instead of using the client but it's the same. Can someone please help me to figure it out?

Thanks
