Erlend Garåsen commented on CONNECTORS-678:
-------------------------------------------
I have already double-checked access credentials. We're only crawling open web
pages. Most of the documents at the university, including protected pages, are
handled by its own Solr connector for our CMS. Anyway:
==> No page access credentials specified
==> No session-based access credentials specified
The only security-related setting is an SSL certificate I have added under the
Certificates tab (totally unrelated to this issue).
SELECT * FROM events;
==> No results.
