LDN - Luminis Developer Network

I am getting the following error message when I am trying to access a portlet channel:

Error accessing /portlet-ids JNDI context.

I am attempting a to access a portlet channel through its functional name from a non-logged-in state using the "goto" URL param. I can access the channel just fine when I AM logged in. But clearly something is getting lost or skipped when the "goto" param comes into play.

Any help here would be greatly appreciated!
