again, this is done with the right VACM configuration.

Below the needed calls for v1, for v2 copy it with SecurityModel_v2.

Map "public" to group "v1v2readgroup":
        vacm->addNewGroup(SecurityModel_v1, "public",
                         "v1v2readgroup", storageType_volatile);

Map "secret" to group "v1v2writegroup":
        vacm->addNewGroup(SecurityModel_v1, "secret",
                         "v1v2writegroup", storageType_volatile);


Give "v1v2readgroup" only access to "v1ReadView":

        vacm->addNewAccessEntry("v1v2readgroup", "",
                                SecurityModel_v1,
                                SecurityLevel_noAuthNoPriv,
                                match_exact,
                                "v1ReadView", "",
                                "",
                                 storageType_nonVolatile);

Give "v1v2writegroup" access to 'v1Read/Write/NotifyView':
        vacm->addNewAccessEntry("v1v2writegroup", "",
                                SecurityModel_v1,
                                SecurityLevel_noAuthNoPriv,
                                match_exact,
                                "v1ReadView", "v1WriteView",
                                "v1NotifyView",
                                storageType_nonVolatile);

Depending on your needs, you can change the configuration for
"v1ReadView" and/or "v1WriteView".
