[Bug 1278738] [NEW] trusts in keystone fail in driver when impersonation is not provided

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

When creating trusts in Keystone, if 'impersonation' is not provided
Keystone fails out in the backend code. This should probably be handed
at the controller level to be consistent across all backends.

lbragstad@precise64:~/curl-examples$ cat create_trust.json
{
    "trust": {
        "expires_at": "2014-02-27T18:30:59.999999Z",
        "project_id": "c7e2b98178e64418bb884929d3611b89",
        "impersonation": true,
        "roles": [
            {
                "name": "admin"
            }
        ],
        "trustee_user_id": "bf3a4c9ef46d44fa9ce57349462b1998",
        "trustor_user_id": "406e6d96a30449069bf4241a00308b23"
    }
}

lbragstad@precise64:~/curl-examples$ cat create_trust_bad.json
{
    "trust": {
        "expires_at": "2014-02-27T18:30:59.999999Z",
        "project_id": "c7e2b98178e64418bb884929d3611b89",
        "roles": [
            {
                "name": "admin"
            }
        ],
        "trustee_user_id": "bf3a4c9ef46d44fa9ce57349462b1998",
        "trustor_user_id": "406e6d96a30449069bf4241a00308b23"
    }
}

Using impersonation in  the create_trust.json file returns a trust
successfully:
