Ad Connector Imports fail with: Object reference not set to an instance of an object

Stephen Nguyen 8 months ago in UNIFYBroker/Microsoft Active Directory updated by Andrew Grant (Software Engineer) 8 months ago 1

The connector is able to push data to AD, but throws an error when performing a change/all import from AD.

Has anyone run into this issue on imports?
