Defines the maximum time (in weeks) beyond the maxage value that a user can change an expired password. After this defined time, only an administrative user can change the password. The value is a decimal integer string. The default is -1, indicating restriction is set. If the maxexpired attribute is 0, the password expires when the maxage value is met. If the maxage attribute is 0, the maxexpired attribute is ignored. Range: 0 to 52 (a root user is exempt from maxexpired)
