- fixes according to new API changes
- closing db connection in connection_destroy callback, not unbind
- support of new schema code, samples changed accordingly

- auto 'ref' attribute support
- samples now include illustrations of using these 2 features to make named referrals as described in ldapext-namedref draft

more to come:
