Resolution

Info on SP-Initiated Logout:

  • This can sometimes be ignored when setting up SSO, which it shouldn’t.
  • Once the customer has logged in successfully, it is important to ask them what their expected logout behaviour is.
  • The customer has authenticated themselves with their Idp whilst logging in.
  • When logging out, they may just want to end the active SP (SuccessFactors) session but remain logged into their Identity provider. In this case, we would set SP-Initiated Logout to ‘No’.
  • This is because the customer may have many other applications besides SuccessFactors using the active Idp session to authenticate them into their various other applications
  • If we set SP-Initiated Logout to ‘Yes’, when the customer logs out of SuccessFactors, they also terminate the active Idp session.
  • This means the user will now be prompted for Idp credentials when they attempt to SSO into another application.
  • Depending on the customers needs, we should set this field accordingly.
  • See the screenshot and definitions below.
