Plugin fails with error undefined #43

Closed rayalex closed 7 years ago

rayalex commented 7 years ago

I've tried setting up this plugin on RabbitMQ 3.6.6, however it seems to be failing with unknown error. HTTP Server logs indicate that request was never received, so it's probably failing before that.

Setup:

Configuration:

[
 {rabbit, [{auth_backends, [rabbitmq_auth_backend_http]}]},
 {rabbitmq_auth_backend_http,
  [{http_method,   post},
   {user_path,     "http://192.168.1.101/auth/user"},
   {vhost_path,    "http://192.168.1.101/auth/vhost"},
   {resource_path, "http://192.168.1.101/auth/resource"}]}
].

Server is configured to always return allow and allow administrator for user path.

Logs:

                                   {line,48}]}]}

Any ideas what might be an issue here?

Thanks.

EDIT:

Resolution: First line of configuration should say {rabbit, [{auth_backends, [rabbit_auth_backend_http]}]}, instead of {rabbit, [{auth_backends, [rabbitmq_auth_backend_http]}]},

Please post questions to rabbitmq-users or Stack Overflow. RabbitMQ uses GitHub issues for specific actionable items engineers can work on, not questions. Thank you.

The error says thatrabbitmq_auth_backend_http:user_login_authentication/3 is undefined. Your config is incomplete and I suspect it may be incorrectly nested. Please take this to the mailing list.

There's plenty of examples of authn/authz backend configurations, including this very plugin, in the docs.

@michaelklishin The issue indeed was in my configuration, thanks.
