Do I have to (re)define my user passwords into the Framework?
In i5/System i based applications the answer is generally no.
In System i/i5 based Framework applications, including RAMP, the validation of a password for a user profile can be performed by IBM i at the point the user accesses the i5/ System i system. For the Framework in general this is typically happens when the user starts a super-server session. For RAMP this is typically done when the user signs on to their 5250 session. In web browser based applications either web server user authentification or a user exit (IIP) can be used to validate the password via the operating system, rather than by the Framework itself.
In Windows applications the answer is generally yes, because user profile management in Windows products is generally much more fragmented.
