[rabbitmq-discuss] [SPAM] Re: [SPAM] Re: Certificate with more than one intermediate CA

The standard openssl s_client and s_server work without problem with these certificates. This problem I believe comes from the Erlang ssl library having default values set on properties that cannot be set through the uri query params. 

From the erlang docs, http://www.erlang.org/doc/man/ssl.html

"{depth, integer()}
The depth is the maximum number of non-self-issued intermediate certificates that may follow the peer certificate in a valid certification path. So if depth is 0 the PEER must be signed by the trusted ROOT-CA directly, if 1 the path can be PEER, CA, ROOT-CA, if it is 2 PEER, CA, CA, ROOT-CA and so on. The default value is 1."

Thanks,

Thomas

Can you connect to the upstream using an ordinary client? If not, follow http://www.rabbitmq.com/troubleshooting-ssl.html to narrow down the problem.

Regarding your earlier question...

There isn't one; the SSL-related URI parameters documented at http://www.rabbitmq.com/uri-query-parameters.html are the only ones supported.
