The purpose of distributed Single sign-on and Single sign-out is automatically sign-in and sign-out to multiple different external services (herein: SSO target) when user signs in to Trivore Identity Service (TIS) via user-interface or OpenID Connect. For example, when user signs in to https://oneportal.t5.fi he/she will also be signed in to https://service1.example ja .org and https://service2.example.com. Every namespace in TIS can have multiple different external SSO targets and sign-on to these targets is completely transparent to user.
