Hello DDP021,
I know some of my customers is using RACF with CMOD.
Concerning the change of password, I don't know exactly how they do it, I should ask them.
Now, what is possible to do, would be to write/modify the security user exit of CMOD in order to allow the changing of password. You need to write a small C code function in order to discuss with RACF and do the change of password.
I see not many other possibilities. I will still try to find out what my customers are doing :-) I'm also curious!
Sincerely yours,
Alessandro
