Introducing an authorization client which is able to determine how to authenticate when it gets a 401 and includes the following headers:
(org.apache.http.Header) [Www-Authenticate: Basic realm="openshift", Date: Wed, 25 Feb 2015 20:11:49 GMT, Content-Length: 0, Content-Type: text/plain; charset=utf-8]
Add method to identify the auth scheme and return the realm. Update the 'canconnect' endpoint to use this function.
This was achieved by trying to auth with empty username and password
