disable password change prompt notifications

[David Mehler]

Hello,

Running Fbsd 11.x. I am getting warning your password will expire on x
day, and that day is 2 and a half weeks away. This happens both on
login and when I use the su command. I'd like to suppress these
password change warnings or at least make them only go off say 3 days
prior to a mandatory password chage.

Any help appreciated.

Thanks.
Dave.
