Why is it not possible to issue a C/R for the user SYSTEM?


In order to assist a user by issuing a Challenge/Response, you must have at least one more user right than the user himself.

The user SYSTEM has all possible user rights by default (and cannot be changed!), thus it is impossible to have a user who has one more user right than the user SYSTEM.
