title: Troubling with MicroStack Command Line API
body: <p>I am facing trouble with Microstack CLI.I did install Microstack twice for the same reason. In the beginning, every command works but after a certain period while working it starts to through the underneath error for each command:
  The request you have made requires authentication. (HTTP 401) (Request-ID: req-fe7ba922-3898-49f8-9441-0624e3b1d241)</p>
  <p>Besides,I would like to know how to change the admin password of the Microstack (Ussuri)?</p>
  <p>I really need to have the solution. Your suggestions are greatly appreciated. Thanks a lot</p>
