[rabbitmq-discuss] Access control

[Andi Constantin]

Hi !

I found a problem in our rabbit:

=ERROR REPORT==== 16-Apr-2011::00:09:24 ===
connection <0.11689.2074> (running), channel 1 - error:
{amqp_error,not_found,"no exchange 'msat.x.mo' in vhost '/'",
             'exchange.delete'}

I guess an application deleted the exchange :(

1. How can i set-up permissions for a user in order to allow queues 
declare and delete but don't allow exchange.delete ?
2. Anybody had that error without an explanation ?

Thanks in advance,
Andi.
