[keycloak-dev] Query on multi Tenancy

Hi Team, I have some query on multi tenancy. Scenario: a) I have a webservice (named: SampleService) that is to be shared across multi tenants , i.e in other words, the service will be present in multiple realms. The number of realms are dynamic, they can be increased based on new client onboard. Configuration: I have multiple keycloak.json files present in resource folder of SampleService such as: realm1-keycloak.json realm2-keycloak.json. TO resolve this multiple jsons, I have a path resolver in web.xml of SampleService: <context-param> <param-name>keycloak.config.resolver</param-name> <param-value>com.crunchify.restjersey.PathBasedKeycloakConfigResolver</param-value> </context-param> b) I have a UI application, that gets authenticated by calling the the service to get the token: example new HttpPost(KeycloakUriBuilder.fromUri("http://localhost:8080/auth") .path(ServiceUrlConstants.TOKEN_PATH).build(realmName)); Now My question is. I have the token for a particular realm(say realm1) and I want to call the SampleService using that token. How will SampleService come to know which keycloakJson to use to resolve the token validation: Note my service call URI doesn't change as per realm: example: URI are localhost:8080/sampleService/getRequsitionDetails or localhost:8080/sampleService/postRequsitionDetails and not localhost:8080/sampleService/realm1/getRequsitionDetails or localhost:8080/sampleService/realm2/postRequsitionDetails. Kindly respond to the above case. Please let me know in case of any issues.
