Whenever I am logging from the portal, in the backend sytem i.e. in SAP, I am getting sy-uname as last logged in user from the portal. We are using single sign-on policy from the portal. I had cleared cache from the portal as well but still didn't work.
Whenever I am clearing the browsing history and logged in from the portal, I am getting correct logged in user as sy-uname in the back end system. But I can't tell user to clear his browsing history each time. So how I can get correct logged in user in the back end ?
Thanks in advance.
