The pam_pwquality module's 'ucredit=' parameter controls requirements for
usage of uppercase letters in a password. When set to a negative number, any password will be required to
contain that many uppercase characters. When set to a positive number, pam_pwquality will grant +1 additional
length credit for each uppercase character. Modify the 'ucredit' setting in
'/etc/security/pwquality.conf' to require the use of an uppercase character in passwords.
Parameter:
[2_upper_char/1_upper_char/0_upper_char]
Technical Mechanism:
Requiring a minimum number of uppercase characters makes password guessing attacks
more difficult by ensuring a larger search space.
