When we try to open the web site from the office document by clicking on link, it redirects to login page but after entering the credentials the authentication is failing, I think this is occuring its due to different sessions one initiated by office document and another by keycloak, in this the due to shred cookies it fails to authenticate at keycloak level, is this issue addressed in keycloak, might be in higher version ? we are using keycloak 6.0.
