Does anyone know what the groupType attribute on the VCACProvisioningGroup is? I noticed that the groupType for all of the groups I've created is 0 whereas there are some other groups that show up in a vCACEntityManager system query that I have not created whose groupType is 1. I want to use the readModelEntitiesBySystemQuery to get all provisioning groups but it returns odd groups that I didn't create. I'm wondering if I can use the groupType to return only the groups I have created.
