Hello there,
I've got an SAML2 Authentication running (IDP = SAP Portal; SP = ABAP HCM) and everything works fine so far.
Now I've got the requirements that this kind of authentication must be used in an kiosk scenario too.
In this scenario only the password is provided for the corresponding employee, the user id is created automatically and must be preset in the logon dialog.
( In the next step an alternate logon dialog should be provided for this case with just the password field visible...)
I'm already able to get the user id, but I've got no possibility to fill in this ID in the logon dialog of my IDP.
I've tracked down the problem, but the only solution I've found so far on ABAP side is to enhance the generated redirect URL to the IDP with the parameter "j_username".
https://idp.server.com/saml2/idp/sso?SAMLRequest=...&j_username=john
Is it possible to define custom parameters for an IDP Redirect-Url or is the only solution to enhance / modify the corresponding class generating this URL?
I'm not very familiar with logon procedures, so other solution hints are welcome, too!
Many thanks in advance.
Greetings
Kai Fischer
