title: MiniKF users provisioning phase fails
body: <p>I'm trying to install MiniKF on my local Mac.
  I followed the instructions listed <a href="https://www.kubeflow.org/docs/started/workstation/getting-started-minikf/" rel="nofollow noreferrer">here</a>.
  After browsing to <a href="http://10.10.10.10" rel="nofollow noreferrer">http://10.10.10.10</a> and progressing with the wizard, I'm getting this error message:</p>

  <p>This error can be seen in the picture below.</p>
  <p>When I'm clicking &quot;Connect to Kubeflow&quot; and entering the username and password as seen in the picture below, I'm getting the error: &quot;Invalid Email Address and password.&quot;.</p>
  <p>Any ideas how to fix that?
