Uh, oh. You will criticize my idea :)
So there is a custom auth backend that extract something from client's
SSL certificate and puts it into user's impl.
Client is obliged to also provide the same information in AMQP headers.
This is done because our server app also needs that data and by the time
message reaches it, there is no SSL anymore.
Since client may put whatever it likes in the header, I want that
RabbitMQ that accepts the message did the validation - compare that
value in the header and the value from user.impl (extracted from SSL
cert) are the same or reject the message otherwise.
So we do not trust AMQP headers we receive from the client but we do
trust the SSL certificate and we do trust AQMP headers after the message
came through the first Rabbit and was verified.
A am also thinking of relaxing the requirements for the client to add
that header in the first place - the custom exchange can add it if it is
I do understand that it violates AMQP specs but it does not look that
