Based on a previous support request I was able to disable read access to wikibase for anonymous users by adding the following on LocalSettings.php.template
$wgGroupPermissions['*']['read'] = false;
Right after that, the query service syncing edits from wikibase. With the current setup, It requires anonymous access to recent changes and page data to work correctly.
Is there a way to pass credential information on the wdqs updater service?
Thank you in advance again for your support
