• The Keycloak Keycloak® Identity Service integration is available from JOC Cockpit:
  • This requires Keycloak® to be installed and operated. Keycloak® is not a built-in Identity Service Provider and does not ship with JS7.
  • JS7 implements a REST client for use with Keycloak® 16.0 and newer.

• Realms/Tokens
  • Access Token Lifespan: After When exceeding the lifespan an access token will expire. The access token is automatically renewed by JOC Cockpit 20s before expiration. If Client Session Idle is shorter than Access Token Lifespan Lifespan then theaccess token will be renewed 20s before Client Session Idle expires.
  • Client Session Idle: After the idle timeout the session will expire. The access token and implicit implicitly the session is are automatically renewed by JOC Cockpit 20s before idle timeout.
  • Client Session Max: After this period a session can no longer be renewed. It is recommended to set this value to a larger value then the session timeout configured in JOC Cockpit.
  • SSO Session Idle: Used when Client Session Idle is not set.
  • SSO Session Max: Used when Client Session Max is not set.

• Keycloak access tokens are created with the following restrictions:
  • Time to Live (TTL):
    • The access token will expire after the given period (Access Token Lifespan).
    • The session will expire after the given period (Client Session Idle).
    • The Identity Service renews the access token 20s before expiration of the session or of the access token, this step is performed until Session Max is reached. This requires that the access token's TTL exceeds 60s and that the Keycloak permission for renewal of an access token by its owner is in place.
  • Maximum Time to Live:
    • The access token's overall lifetime is limited (Session Max), renewals cannot take place after the specified period.
• If an access token cannot be renewed by the Identity Service then the user session is terminated and the user is forced to login and to specify credentials.
  • This happens in the event that the maximum TTL is exceeded or that the token is revoked.
  • Keycloak administrators should check for reasonable values of the session TTL (Session Idle) and the Access Token Lifespan, maybe not less than 300s, and the maximum TTL (Session Max) , maybe typically at least 15 minutes, as otherwise users will have to repeatedly login quite frequently.
• The JOC Cockpit handles the idle timeout of user sessions independently from Keycloak, see JS7 - Identity Services.
  • If the idle timeout is exceeded then the user session is terminated.
  • The Identity Service will revoke the access token with the Keycloak Server on termination of the user session.
