Modify ldap_result to assert returned error is not an one reserved for API use. Modify frontend LDAP operation routines to return an error code. The returned value will be used to determine if an unsolicited notification should be sent to the client. Need to review returned error codes. Namely some LDAP_PROTOCOL_ERROR will like need to be changed (as they will cause unsolicited notifications).
