Ensure that the SETROPTS PASSWORD(HISTORY) value is set to a minimum of 5

Descripción

HISTORY specifies the number of previous passwords that RACF saves for each user ID and compares with an intended new password. If there is a match with one of the previous passwords, or with the current password, RACF rejects the intended new password. A password history policy prevents users from immediately reusing an old password by enforcing a minimum number of new, unique passwords that must be used before a previous one can be reused.
