title: How to use the <secret> tag in the remote_servers tag?
body: <p>I am modifying the remote_servers tag in config.xml.</p>
  <p>Most of the setup was done with the help of stackoverflow.
  thank you.</p>
  <p>However, when I use the secret tag in the cluster configuration, I get an error.</p>
  <p>Below is an example of the settings I have configured.</p>
  <pre><code>&lt;clusters&gt;
      &lt;secret&gt;same_user&lt;/secret&gt;
      &lt;shard&gt;
          &lt;replica&gt;
              &lt;host&gt;127.0.0.1&lt;/host&gt;
              &lt;default_database&gt;local&lt;/default_database&gt;
              &lt;port&gt;9000&lt;/port&gt;
          &lt;/replica&gt;
      &lt;/shard&gt;
      &lt;shard&gt;
          &lt;replica&gt;
              &lt;host&gt;remote1&lt;/host&gt;
              &lt;default_database&gt;local&lt;/default_database&gt;
              &lt;port&gt;9000&lt;/port&gt;
          &lt;/replica&gt;
      &lt;/shard&gt;
      &lt;shard&gt;
          &lt;replica&gt;
              &lt;host&gt;remote2&lt;/host&gt;
              &lt;default_database&gt;local&lt;/default_database&gt;
              &lt;port&gt;9000&lt;/port&gt;
          &lt;/replica&gt;
      &lt;/shard&gt;
  &lt;/clusters&gt;
  </code></pre>
  <p>All shard is using the same user and same password.</p>
  <p>Also, the user connected as clickhouse-client to execute the query is the same.</p>
  <p>But when I execute SELECT COUNT(*) FROM distributedTable in clickhouse-client , an error occurs.
  error is
  <code>Code: 101. DB::Exception: Received from localhost:9000. DB::Exception: Received from remote1:9000. DB::Exception: Hash mismatch.</code></p>
  <p>This is a query that works fine if i enter the <code>&lt;user&gt;, &lt;password&gt;</code> tag without using the secret tag. Is there a cause? I'm using the 20.11.7 version.</p>
  <p>Please help if there is a way.</p>
  <p>thank you.</p>
