Regarding docs, sessions and cache

,
1

Hi, I have a couple of questions. I would appreciate your help. I am planning to use Keycloak Quarkus

  1. I want to create a custom authentication SPI. Although the doc walk you trough, I don’t find any documentation explaining what java objects I have access to and their intention. Where could I find it?

  2. I have a specific use case for some users where a main IDP will delegate authentication to Keycloak. Once the user is authenticated, Keycloak will create a SAML assertion and send the data to this IDP. The main IDP will handle the sessions and thus I don’t want to keep alive sessions in Keycloak. Is there a way to log in users and don’t create a session? Or a workaround to this?

  3. In the docs of Keycloak Quarkus I didn’t find anything regarding distributed cross-site cache. I might not use Kubernetes. I might deploy in different availability zones using EC2. So how can I achieve this?

Thanks for your help!
