Problem: Basic Authentication doesn't appear to be working when pointing to external source (auth broker). I'm seeing this function just fine when I revert from "Authentication: External Provider" back to "Authentication: Basic" and using the internal Atom-based authentication. Connectivity looks OK -- I'm able to telnet from one of the receiving web service nodes to the auth broker (on port 8080).
Is there anything tricky or good to look for in order to troubleshoot Auth Broker? I cannot see requests land in the auth broker container logs.
