Shib Session Management Information

  • Shib sessions implicitly establish CAS sessions, but not vice versa.
    • Implications: 
      • If you first log into Shib (say for Gmail), you can later seamlessly SSO to CAS sessions.
      • First logging into CAS will not seamlessly SSO to a Shib session.
  • Successful authentication to Shib grants user a Ticket Granting Ticket (TGT) to be used for SSO.
  • TGT idle timeout: 2 hour sliding window.
  • TGT hard timeout: 8 hours from date of TGT creation.
  • Each application maintains its own session state.
