Can't get an X-Storage-Url and X-Auth-Token

Hi,
Im testing a Swift environment and everything works perfectly except the "curl" command to get an X-Storage-Url and X-Auth-Token. I am using keystone in another host to authenticate. This is what i get :

[root@SWIFT-MACHINE ~]# curl -k -v -H 'X-Storage-User: admin:admin' -H 'X-Storage-Pass: cloud' http://192.168.224.248:5000/v2.0
* About to connect() to 192.168.224.248 port 5000 (#0)

When using the "swift" commad to get stats on my accounts, objects and containers as well as to upload or dowload object, everything works smoothly.

Thanks in advance for your help.
