2544749 - Single Sign On authentication doesn't work as expected for Browser access to Application Server ABAP


You want to use Single Sign On (SSO) e.g. using X.509 certificate, SAML or SPNego for authentication to Application Server ABAP system, you did the configuration of the SSO, but it doesn't work as expected. Maybe you see:

  • Logon page
  • Logon popup
  • Logon failed page
  • You have to refresh the page to get logon 
  • No redirect to SAML Identity provider 

If you remove all other logon procedure from the logon procedure list in transaction SICF, the SSO is working well.
