Using JavaScript to get an LDAP multi-valued string attribute

Question

I am trying to retrieve an object attribute in Active Directory that appears to be a multi-valued string (See canonicalName). After performing a search:

var conn;
conn.Open = 'Provider=ADsDSOObject;';
var command = '<LDAP://CN=Partitions,CN=Configuration,DC=domain,DC=com>;(&(objectcategory=crossRef)(systemFlags=3));name,nETBIOSName,nCName,canonicalName;onelevel';
var ado = new ActiveXObject('ADODB.Command');
ado.ActiveConnection = conn;
ado.CommandText = command;
var records = ado.Execute;

and while looping through the recordset:

while (!records.Eof){
  ...

  records.MoveNext();
}

I then try and get the canonicalName:

var cn = records.Fields('canonicalName').Value;

The problem is that JavaScript doesn't intrepret cn as a string or as an array... if you look at the AD schema for the canonicalName you can see it's configured with 'isSingleValue = false' which is what I believe is causing the problem...

When stepping through the code with Visual Studio I can drill into the string value and the QuickWatch shows cn.value(0) as returning the string value. But when I type that out it doesn't work...

I have tried the usual ways to get the value without luck:

for (var i in cn) { alert(cn[i]); }

and

for (i = 0; i < cn.length; i++) { alert(cn[i]); }

Neither works...

How can I read the value of this object?
