Realized that when we reset the password to one of the entries exists in USR40, the system will pop up a warning and said that the password is in exception table.
however, after I hit Enter, the system still allow me to reset the password which is exists in exception table.
E.g. password : 123456 is in the USR40. When I reset my id to 123456, a warning pop up and i hit enter, now my password is 123456.
What does this Exceptional table did actually ? Suppose all the passwords in USR40 is restricted to use? But how come I can still use the excepted password ?
