Updating security settings with JSON for mixed mode security (AD Groups/ArcGIS Users)

[AlexPerez]

I need to update my ArcGIS Server settings but need to do so with JSON code as I have to specify my domain controller as well.  Instead of using "WINDOWS" as the "type", what value should I use for mixed mode (windows/arc users)?  Here is the code I was using for Windows security but I cannot find the keyword for combined AD/ArcGIS security.

{
"type": "WINDOWS",
"properties": {
"adminUserPassword": "+4qrQMQxzq4ubfdDDFcXjQ==",
"domainControllerAddress": "10.1.1.1",
"adminUser": "domain\\account"
}
}
