Not Returning objectSid for groups?

[alberto360]

pulling for groups and I can't seem to get the following attributes:

• objectGUID
• objectSid

here is the snippet

    var ad = new ActiveDirectory(domainConfig);
    var query = 'CN=*';
    ad.findGroups(query, function (err, result) {
        if (err) {
            console.log(err);
            log.error("No Groups found.");
        }
        log.info(result);
    });

am I missing something?
by default the all attributes are returning, correct?

attributes - attributes to select and return (if these are set, the server will return only these attributes). Defaults to the empty set, which means all attributes.
