Those should all be sans mq, since they refer to module names. So the 
second one is wrong.

Correct. This is referring to the app/plugin.

You'd get the above if the auth_backends config entry contained 
rabbitmq_auth_backend_ldap, which, as per the above, should be 
rabbit_auth_backend_ldap instead. That's what you have in the config you 
posted though, so I suspect the error is from a different run.
