He also quickly got the password for various RFC users via the radio ("As long as passwords are only communicated by phone and never exchanged in writing, we are clean!"). And that the RFC users are generously entitled even in productive systems is no longer a secret ("Better to have more permissions than too little; the RFC connections have to run, otherwise there is trouble from the specialist areas!").
