title: Redis Sentinel Authentication
body: <p>I have 3 Servers with Redis and Sentinel Running. 
  All instances have in the configuration </p>
  
  <pre><code>requirepass XXX
  masterauth XXX
  </code></pre>
  
  <p>I can connect with redis-cli to the redis server but if I try to connect to the sentinel I can not authenticate.</p>
  
  <pre><code>root@ip-:/usr/lib/nagios/plugins# redis-cli -p 26379
  127.0.0.1:26379&gt; AUTH xxx
  (error) ERR unknown command 'AUTH'
  127.0.0.1:26379&gt; 
  </code></pre>
  
  <p>If I use the same command but with the redis port it works.</p>
  
  <p>Thanks
  best</p>
