[rabbitmq-discuss] Using rabbitmq_auth_mechanism_ssl with the .NET client

[John Ruiz]

I have a certificate with the following Subject:
"CN=John Ruiz, CN=Users, DC=devexample, DC=com"

When you look at rabbit_ssl.erl's find_by_type function, (this is my
first time seeing erlang code, btw) I notice that there's a "<-
lists:flatten(RDNs)" line.  I don't know what the result of
lists:flatten will be.  This is probably why the connection suddenly
ends... the user I've created for rabbit isn't matching what the cert
says.

Can anyone help me?
