The pam_cracklib module's "lcredit=" parameter controls requirements for usage of lowercase letters in a password. When set to a negative number, any password will be required to contain that many lowercase characters. When set to a positive number, pam_cracklib will grant +1 additional length credit for each lowercase character. Add "lcredit=-1" after pam_cracklib.so to require use of a lowercase character in passwords. |
