# Password aging controls:
# PASS_MAX_DAYS Maximum number of days a password may be used.
# PASS_MIN_DAYS Minimum number of days allowed between password changes
# PASS_MIN_LEN Minimum acceptable password length.
# PASS_WARN_AGE Number of days warning given before a password expires
PASS_MAX_DAYS 99999
PASS_MIN_DAYS 0
PASS_MIN_LEN 5
PASS_WARN_AGE 7
Why is it 99999 days? 5 nines. What is special about this? Does it have to be 5 characters? It coulda been 9999, even 999 days. I feel like there's a reason it is 99999.
I realize this doesn't matter for function, but I am curious as to why. If there is no reason, I want to know that too.
