[rabbitmq-discuss] RabbitMQ Federation & SSL

Fri May 24 22:55:07 BST 2013

Simon,

Again, thank you for your continued help. I have made progress, but I'm 
hitting another problem.

I'm trying to establish federation between two brokers (one happens to 
be clustered, but the second cluster node is currently down) using 
passwordless-SSH using a LDAP authentication backend. If I disable 
external auth, I can get the federation clients to connect. Once I 
enable external auth, I get the following error. Any ideas?
