Arthur was actually very close, the last remaining hurdle was to reconfigure 
RabbitMQ with the right username, password and vhost. The chef-server 
cookbook shows how to do this: 
https://github.com/opscode/cookbooks/blob/master/chef-server/recipes/rabbitmq.rb#L56-69

The RabbitMQ docs explain that this happens because the config database is 
stored in a directory named after the system's hostname[1]; I'm not sure why 
RabbitMQ works this way.
