cannot create user - 401 unauthoroized

I'm doing a PUT to /v2.0/users as ADMIN

    eventlet.wsgi.server: DEBUG 127.0.0.1 - - [15/Jun/2011 14:42:11] "PUT /v2.0/users HTTP/1.1" 401 210 0.005239

But it fails with 401 Unauthorized.

Updating the code to print the request before creating

    @utils.wrap_error
    def create_user(self, req):
        print 'req %s' % req
        user = utils.get_normalized_request_content(users.User, req)
        print 'user %s' % user
        print 'user.tenant_id %s' % user.tenant_id
        return utils.send_result(201, req,
                       service.create_user(utils.get_auth_token(req), \
                                        user))

Shows that I'm tenant_id isn't being set:

    {"user": {"tenant_id": "1234", "password": "asdf", "enabled": true, "id": "jesse", "email": "<email address hidden>"}}
    user <keystone.logic.types.user.User object at 0x101e58bd0>
    user.tenant_id None

Looking at logic/service.py:

        dtenant = db_api.tenant_get(user.tenant_id)
        if dtenant == None:
            raise fault.UnauthorizedFault("Unauthorized")

Shows the exception.

Expected:

   A user is created with primary tenant of 1234

Actual:

   401 unauthorized

If the tenant is missing we should raise a BadRequestFault("Expecting a Tenant")?

        if not isinstance(user, users.User):
            raise fault.BadRequestFault("Expecting a User")
