  • One system must be configured as the ticket-issuing system.
  • Other SAP systems must be configured to accept logon tickets (and therefore preconditions for logon ticket configuration or non-logon ticket configuration, such as certificate, must be met prior).
  • Usage of Secure Network Communications
