PAM module pam_passwdqc module

Hello friends

Today i have changed my passwd policy for strong password

Everything is working correctly but when i changed my password , it did not ask me my old password

my /etc/pam.d/system-auth file is (only passwdqc.so module line)

password required pam_passwdqc.so retry=3 ask_oldauthtok=update check_oldauthtok min=disabled,16,11,8,8 enforce=none max=25

Problem is ask_oldauthtok and check_oldauthtok argument is not working

Any Help
Thanks
