Bug Description

Binary package hint: libpam-ccreds

This is partly related to #294977.

- User logs in, ccreds caches the "old password"
- User changes the password
- Then the user goes offline without logging in again

This scenario leaves the old password valid when offline, and the new password invalid.

Should this be reported upstream? Or can libpam-ccreds used in common-password to "store" the password on success?

As also pointed out in #294977, this is a security issue if the old password has been compromised.
