Comment 32 for bug 272232

I still see this on my updated Intrepid system (dist-upgraded from edgy to hardy to intrepid), i.e.:
"Sorry, passwords do not match
passwd: password updated successfully"

Longer session with initial warning for password 'too simple':
ubuntu:~$ passwd
Changing password for sysuser.
(current) UNIX password:
Enter new UNIX password:
Retype new UNIX password:
Bad: new password is too simple
Enter new UNIX password:
Retype new UNIX password:
Sorry, passwords do not match
passwd: password updated successfully

 /etc/pam.d/common-password :
$ egrep -v '#|^$' /etc/pam.d/common-password # removing '#' and empty lines
password [success=1 default=ignore] pam_unix.so obscure sha512
password requisite pam_deny.so
password required pam_permit.so
