I know is kinda misleading, but ldap_unbind is not the opposite of ldap_bind;
it is rather a "connection shutdown" operation. If you need to revert to
an anonymous binding, you may simply rebind with empty dn and credentials;
if you need to close a connection, then use ldap_unbind, which is always
synchronous and instantaneous; remember that you cannot use the LDAP*
descriptor any more; you need to re-initialize it (ldap_init).
