SAP Business ByDesign.

Reproducing the Issue

Try to access the SAP Business ByDesign with SSO configuration.


It migh have two different causes for this scenario:

  1. ACS URL, where it's not correct as per the SP metadata file.
  2. The other possibility is related to the Include Assertion Consumer Service URL, where it's wrongly selected.


  1. Please change the ACS endpoint according to the SP metadata, for example: ''
  2. Please uncheck the 'Include Assertion Consumer Service URL' option that is maintained in the Configure Single Sign-On View and then Identity Provider screen.
