title: "User "system" cannot get securitycontextconstraints at the cluster scope" in Openshift3
body: <p>If I try to add a security constraint to a local OpenShift all-in-one cluster running in Windows10 Pro and Hyper-V, openshift client receives the following message:</p>
  
  <pre><code>c:\openshift\oc.exe adm policy add-scc-to-user anyuid -z default
  Error from server (Forbidden): User "system" cannot get securitycontextconstraints at the cluster scope"
  </code></pre>
  
  <p>The Openshift instance was created by docker machine using the following steps:</p>
  
  <pre><code>1) docker-machine create -d "hyperv" --engine-insecure-registry 172.30.0.0/16 --hyperv-virtual-switch "openshift" openshift 
  2) oc cluster up --docker-machine=openshift
  </code></pre>
  
  <p>Is there any configuration to allow system user to have access to securitycontextconstraints?</p>
