title: this command is not available unless the connection is created with admin-commands enabled
body: <p>When trying to run the following in Redis using booksleeve. </p>
  
  <pre><code>using (var conn = new RedisConnection(server, port, -1, password))
  {
      var result = conn.Server.FlushDb(0);
      result.Wait();
  }
  </code></pre>
  
  <p>I get an error saying:</p>
  
  <blockquote>
    <p>This command is not available unless the connection is created with
    admin-commands enabled"</p>
  </blockquote>
  
  <p>I am not sure how do i execute commands as admin? Do I need to create an a/c in db with admin access and login with that?</p>
