title: RabbitMQ Admin Can't Log In To Management UI
body: <p>I am running RabbitMQ version 3.7.6 in a Docker container. The management plugin is enabled.</p>
  
  <p>I receive the following error when logging in to the management UI:</p>
  
  <p><a href="https://i.stack.imgur.com/iqv1z.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/iqv1z.png" alt="enter image description here"></a></p>
  
  <p>I am using the following <code>rabbitmq.conf</code>:</p>
  
  <pre><code>default_user                    = admin
  default_pass                    = redacted
  default_user_tags.administrator = true
  default_user_tags.management    = true
  </code></pre>
  
  <p>The confusing part is that it appears user <code>admin</code> does indeed have management enabled. The following is shown during boot up:</p>
  
  <pre><code>Creating user 'admin'
  Setting user tags for user 'admin' to [management,administrator]
  Setting permissions for 'admin' in '/' to '.*', '.*', '.*'
  </code></pre>
  
  <p>As requested, here is the output of <code>list_users</code>:</p>
  
  <pre><code>$ rabbitmqctl list_users
  Listing users ...
  admin   [management, administrator]
  </code></pre>
  
  <p><strong>Why am I unable to log in to the management console on an account that appears to have the <code>management</code> tag enabled?</strong></p>
