Fix Recommendation

Configure Ubuntu 24.04 LTS to disable account identifiers after 35 days of inactivity after the password expiration.

Run the following command to change the configuration for adduser:

$ sudo useradd -D -f 35

Note: DOD recommendation is 35 days, but a lower value is acceptable. The value "0" will disable the account immediately after the password expires.
