Yes you have perfectly understood what I mean. Ok thanks From: Stian Thorgersen [mailto:sthorger@redhat.com] Sent: Wednesday, October 28, 2015 1:00 PM To: Notarnicola, Mara <M.Notarnicola(a)klopotek.it&gt; Cc: keycloak-user(a)lists.jboss.org Subject: Re: [keycloak-user] info about sso without login prompt Not exactly sure what you are doing here, but I assume you are using direct grant (or resource owner password credential grant as oauth2 calls is) to exchange a username+password for a token? If so that will not support SSO. To enable SSO you must use the proper redirect based login and have your users login through Keycloak's login page.

I need to integrate a previous system of authentication with this new one. To do this, I use user’s credentials passed by the old system, to automatically retrieve keycloak grant calling the related web service. So I have the session data but I’m not able to use single-sign-on in fact when I open another tab the user isn’t logged in anymore. I need to know if there is a way to create a sso session, if I must use cookies or browser local storage.
