Unable to create anonymous user

Thanks Dmitri, appreciate the effort. You might have a point there. I think
it indeed does have to do with our Nginx configuration. Stanchion is
communicating with nginx as a proxy to our riak nodes. I just tested out
pointing stanchion directly to one of our Riak nodes and the admin user
creation went through. You're a hero. Need to debug the Nginx proxy.
