Can I change or add custom fields/Attributes to be imported through the Microsoft Active Directory connector?
In each AD Import Rule for Users and Computers, there is a section called Column Mappings. The Column Mappings can be changed to import data that is not currently being imported.
If none of the Column Mappings make sense for the current options, a new data class can be created and added to the resource being imported (Computer or User Resource types) using the steps below (this requires Asset Control Solution):
