Getting "pam_unix(sshd:auth): authentication failure" when updating password after password expires

Question

When I expire a users password with chage -d 0 USER the user is able to log in and they are prompt with Current Unix password. When the user puts anything into the password the session is closed. inside the /var/log/secure there is a log entry pam_unix(sshd:auth): authentication failure

If the user manually sets a password after I reset their password they have no issues.

What can I look at to solve this issue where expire causes pam_unix to freak out and prevent the user from updating their expired password?
