Hi All,
We’re implementing SSO across multiple applications using keycloak. Some of these applications are traditional java web apps and some are single page javascript apps. For the java web applications, we’re using standard flow and we’re
using the “Spring Security Adapter” to implement this.
One of the use cases we have to support is, when a user goes to the landing page of a web application, the header should show if the user is already logged in or not. When a user has logged in from a different application and then navigates
to another application using a bookmark, they’re accessing a non protected url. The user wouldn’t have an authenticated session with the web application yet, so how can we tell if the user has already logged in from the previous application? They would already
have a session with the keycloak server.
It seems this is possible from single page applications using the keycloak javascript adapter with the “check-sso” initialization option, but it is not clear how this can be achieved from a traditional web application using the “Spring
Security Adapter”. Any suggestions would be appreciated.
Cheers,
Anthony Fryer
