title: How to allow Single Sign-On for al clients in keycloak
body: <p>I am doing the integration for different platforms and I am using keycloak as IDP.
  I have created for each platform different clients which are using SAML protocol. I have the users in keycloak matching with user details in my systems, so now I need to do SSO for all the clients when I do login with a common user, means I have system A, system B, and system C, now I have for example user example@example.com which is a common user by all the systems. Once I logged in into system A with the credential of user example@example.com I need to be logged in system B and system C as well. It's working separately for each system</p>
