[keycloak-user] Keycloak to secure web applications deployed in glassfish

Hi All, I have some web application deployed in glassfish. And we are trying to implement SSO using keycloak. I wanted to understand if keycloak secures and provides sso support for applications deployed on glassfish or if it is applicable to applications deployed on jboss only? I tried to secure a glassfish web application using keycloak [specifying the keycloak pom dependanies, keycloak.json and related entries in web.xml]. but I could not see the direction happening to keycloak for authentication. Am I missing something here? Appreciate any pointers. Regards Prasad
