Many thanks for coming back and for pointing out the Excluded Serial Number & User pairs exception.
This slightly differs from our original requirements however this approach is actually far more secure. From what I understand this pairs a fully qualified user name with the serial number of a particular device. Our original intention was to pair members of an AD group with the ability to write to a configured device definition. From what I can gather this is not possible. Am I correct?
If this is the case, I intend to propose SN & User pairs. I assume you are able to pair a SN with multiple users?
Thanks in advance,
