I'm running into a unique problem when trying to log out of Fiori Launchpad. We have done the configuration to point the logoff page back to the Fiori Launchpad:
Go to node: /sap/public/bc/icf/logoff
Error Pages -> Logoff Page-> Redirect to URL : /sap/bc/ui5_ui5/ui2/ushell/shells/abap/FioriLaunchpad.html
BUT, when we click the button to log off, we are automatically logged back into the launchpad. It's like the session is not killed before the login page has a chance to reload.
We have configured the ushell to point to the pretty Fiori login page as well (/UI2/CL_SRA_LOGIN).
We DO NOT have SSO set up either.
Hope this makes sense.
