As a preface, let me call out that we use numeric UserIDs in our organization.
I am looking to create UI5 based XS applications on SAP HANA. I would like to expose/embed links to these applications in our Enterprise Portal. I want to enable Single Sign on so that once someone is authenticated in the Enterprise Portal, they are not prsented with an additional logon screen when they access content in the EP which is hosted on SAP HANA.
Now from what I understand there are standard ways of establishing trust relationships and configuring HANA to accept the MySAPSSO2 ticket generated by the portal. However I believe that requires the exact same userID to exist on Portal and HANA. This is not possible, as HANA does not allow numeric userIDs which is a standard in our organization.
What can I do to achieve my desired result?
