[rabbitmq-discuss] Error trying to configure rabbit_auth_backend_ldap

[Eric Cozzi]

I am trying to configure rabbit_auth_backend_ldap as a backing auth for 
passwordless login using rabbitmq_auth_mechanism_ssl, but I am getting 
the following error. I've also included my rabbitmq.config file for 
reference.

Any help would be appreciated.
Thanks,
Eric
