title: Nexus manager, npm 401 Unauthorized
body: <p>I'm trying to set up a nexus repository manager.</p>
  
  <p>I have 3 npm repositories, private, proxy and a group of both (see images). Also I attached role's privileges and this is my .npmrc file:</p>
  
  <pre><code>registry = http://127.0.0.1:8081/repository/npm-group/
  email = user@mail.com
  always-auth = true
  _auth = ZGV2OjEyMzQ1Ng==
  </code></pre>
  
  <p>When I try to do a "npm install" I get this error: </p>
  
  <pre><code>npm ERR! code E401
  npm ERR! 401 Unauthorized: gulp-twig@^0.5.0
  </code></pre>
  
  <p>Without nexus, install ends successfully. I'm using this <a href="https://github.com/zualex/frontend-template" rel="nofollow noreferrer">project template.</a></p>
  
  <p>Any idea? What I'm missing?</p>
