title: Using Jfrog access token with docker login
body: <p>I want to run something like:</p>
  <pre><code>$ TOKEN=$(curl -u &lt;my-name:my-password&gt; -X POST &lt;my-jfrog-artifactory-url&gt;/api/security/token -d &quot;username=my-name&quot; -d&quot;scope=member-of-groups:&lt;???&gt;&quot;)
  $ docker login &lt;my-jfrog-registry&gt;
  Username=my-name
  Password=$TOKEN
  </code></pre>
  <p>When generating a token with full admin privileges (using curl above, or via UI), this works. I wanted to know what are the minimal permissions I need to give to a user for him to use this token for login, but couldn't find any documentation on this.
  What should I pass in <code>scope=member-of-groups:&lt;???&gt;</code> above? Create a group with what permissions?</p>
  <p>Thanks!</p>
