Hello this is my frist question here (yaay :D)

I installed Openstack on my CentOS 6.3 Server... It still worked for 1 month... but since last week I can't login with the admin user.... I tried to reset the password with this command

curl -s -X POST -H "X-Auth-Token:999888777666" -d '{"changePassword": {"adminPass": "newPass"}}' http://localhost:8774/v1.1/openstack/servers/3/action__ (http://localhost:8774/v1.1/openstack/servers/3/action)

but i get this as answer:

401 Unauthorized

This server could not verify that you are authorized to access the document you requested. Either you supplied the wrong credentials (e.g., bad password), or your browser does not understand how to supply the credentials required.

Authentication required

Can someone help me?
