So you are saying that she was able to login at the same machine
with the new and old password? Or that she is able to login on
some machines only with the old password and on others only
with the new one?

The first case is impossible.

For the second case, I would bet that this machines have a local
copy in /etc/passwd or /etc/shadow of this accounts with the old
password, and are not using the LDAP account. Or did you enable
some caching modules like pam_ccache on that machines?
