There is caching within RabbitMQ itself, at the channel level. Any 
channel will only check a given permission for a given object once.

There isn't any LDAP-specific caching. In fact at the moment we don't 
even pool LDAP connections.

If you put rabbit_auth_backend_internal first in the list, yes.
