Hey guys,
I had the same Problem.
There are some missing informations in the documentation.
If you want to configure the SSO, you have to login in the application.
If you deploy on sandbox environment, change the variable "AllowLocalLogins" in th "SiemensSecurityIntegration" Module to true. Afterwards deploy again and you can login with the demo users as described above.
If you want to do this on other environment, you can change the variable in the evnironment settings in the deployment settings.
After configure the SSO Modul, you should change the variable again to false.
I deployed on cloud.
I tried with demo_administrator and got failure as well.
I clicked "publish", I got Error code: ERR_NOT_ENOUGH_PERMISSION.
Thank you for your time and help.
Best regards
Li Dong
