How to configure Alfresco Community 7 with a multi-tenant Keycloak
I have a Docker setup consisting of an Alfresco Community 7, two PHP frontend that interacts with a Java backend that acts also as a REST client for alfresco.
Architecture has been secured with Keycloak SSO instance, configured with OIDC and multiple realms, with different login and identity providers for each one.
Alfresco run with a single-tenant configuration because data is shared among all users on both frontend, so users logged in frontend A can access resources created by users from frontend B and vice-versa.
So I can successfully configure Alfresco and Keycloak to use a single realm and interact with those, but I can't find any information about how to use Keycloak multi-tenant configuration with Alfresco.
