Depends what you mean by "the password". RabbitMQ will use the password 
you configured in {other_bind, {diruser, dirpassword}} to talk to the 
LDAP server. But on the AMQPS connection there won't be a password 
transmitted at all.

You'll also need to tell your client to use the EXTERNAL SASL mechanism 
- e.g. in the Java client you would:

     ConnectionFactory factory = new ConnectionFactory();
