Authentication was available false after CVO reported success:
Mar 28 23:32:57.986: INFO: Operators still doing work: <nil>/authentication
I am aware that the authentication CO is the last to become available. Looking into this, I see that cluster-authentication-operator is reporting Available=False and Failing=True when those should instead be Progressing=True. Working up a PR for it.
https://github.com/openshift/cluster-authentication-operator/pull/105 will resolve
$ oc get co authentication
