title: Can I connect one service account to multiple namespaces in Kubernetes?
body: <p>I have couple of namespaces - assume <code>NS1</code> and <code>NS2</code>. I have serviceaccounts created in those - <code>sa1</code> in <code>NS1</code> and <code>sa2</code> in <code>NS2</code>. I have created roles and rolebindings for <code>sa1</code> to do stuff within <code>NS1</code> and <code>sa2</code> within <code>NS2</code>.
  What I want is give <code>sa1</code> certain access within <code>NS2</code> (say only Pod Reader role).</p>
  
  <p>I am wondering if that's possible or not? </p>
