[treydock]

Fixes #279

@jonathanmarsaud Would you be able to test this? This should print extra logging about the path being used.

@treydock Thanks, I tested it and now I have:

@jonathanmarsaud Try testing again. I think I fixed the relative path handling for validator.

[treydock]

I added an acceptance test that validate this now works

  Notice: Unable to connect to keycloak server (http://localhost:8080/auth/realms/master/.well-known/openid-configuration): Failed to open TCP connection to localhost:8080 (Cannot assign requested address - connect(2) for "localhost" port 8080)

Once the service was started those cleared up and things worked fine.
