Keycloak user here! You don’t need** LDAP to use keycloak, but you can use it (I do too). Afaik keycloak is not always the easiest (not always clear instructions) but it works flawlessly for me and those who I authenticate. I use it for almost all my self hosted services except those who don’t support it (obviously).I can manage my users in LDAP and use keycloak for SSO etc. I would definitely recommend it!

I used all-minilm which worked well for documents. But it doesn’t work for images (or didn’t when I was using it last time). Although I did in combination with N8N and Qdrant.

I can confirm this. Although the “Europese (producten) kopen” doesn’t work without the “producten”. In that case it would become “Europees kopen” (European buying) or “Europees inkopen” (European purchasing)

Plus one for Keycloak here. Initially it may be a bit daunting but once it’s set it’s a rock and works flawlessly!
