We have RAR 5.2 installed and analyzing various backends (we have ECC5, ECC6 etc.) The user that I`m using to establish conneciton between the Netweaver and the ABAP is of communication type. It is working for all ABAP backends except our CUA client (netweaver 04). For the CUA client the password for the user is expiring every two days. I couldn`t find explanation why is this happening and I`m willing to change the user type to "system" for which I`m sure it won`t have password expiration problems, but i`m not sure what will be the impact on the application.
Please advise me what kind of user type you are using for your user who is connecting to the backends?
