Using the SYSTEM Login, but chekcing uname and pword stored in an Z Table
I developed a BSP Application for a client and also implemented SSO2 and the SYSTEM login. I made a copy of the pages in the SYSTEM Application to my BSP Application. Now, the customer wants the users to login, using username and password stored in an Z Table. He doesn't mind, even if the password is not encrypted. Can someone please guide me, how I can still use the SYSTEM login, which is copied to my application, but check for username and password in an Z Table? Also is it possible to use the same Password Change option? Can I take a copy of CL_BSP_LOGIN_APPLICATION to ZCL_BSP_LOGIN_APPLICATION?
I want to mainly use the SYSTEM login application, because, I want to use the SESSION. Otherwise, clicking on the Back button of the browser even after Logout, will display the contents.
