title: What is the correct way to configure apache superset to connect to presto via LDAP?
body: <p>I started a new Apache Superset deployment from their docker-compose.</p>
  <p>My connection string looks like this:</p>
  <pre><code>presto://user:password@presto:8446/
  </code></pre>
  <p>And in Advanced/Security I put this:</p>
  <p><a href="https://i.stack.imgur.com/OAAMa.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/OAAMa.png" alt="Apache Superset - Security" /></a></p>
  <p>But this doesnt seem to work.</p>
  <p>Any ideas what I am doing wrong? I tried to follow the <code>pyhive</code> connection string as much as possible.</p>
  <p>And yes... PyHive is installed in my docker image. I checked.</p>
  <p>When I click on &quot;Connect&quot; I am getting this error.</p>
  <pre><code>An error occurred while creating databases: (database_name) A database with the same name already exists
  </code></pre>
  <p>When I click on &quot;test Connection&quot; i get the following error</p>
  <pre><code>ERROR: (builtins.NoneType) None
  (Background on this error at: http://sqlalche.me/e/13/dbapi)
  </code></pre>
