We are currently in the process of implementing Fiori apps for HR (Timesheets etc.). We have SAP Gateway as separate instances (ABAP) and are using the usernames from the Gateway to log in. This however is not too convenient as there is a new username/password combo to remember.
What other options for login are there ? I know there is SAP Single sign-on product (with license costs).
Are there other options for single sign-on ? Is Active Directory sign-on possible ?
