[keycloak-user] SSO with multiple domains

Hello, We have 4 different applications, hosted on 3 unique servers. All applications are protected by KeyCloak. All apps are built on AngularJS. In cases where we have multiple tabs open (one for each application) in Chrome. When users logout from one Tab, the other tabs don't always logout. Post this, applications that we login to keep getting unauthorized, and I assume that the tokens have been invalidated. I've tried version 3.0 and 3.2.1. I'm looking for any guidance and best practices to handle such cases. Regards, Ushanas.
