Our AD has this value in the objectSid on a group, user, whatever imported from AD:objectSid: S-1-5-21-2126658991-319633822-626671869-29753In AD this is a binary value. In Insight TextArea field, this is saved: �=�~�9 �@Z%1tI cannot save this value in a Insight field called objectSid. E.g: Someone renames a group in AD, so this renamed group is added as a new object in Insight when CN is the identifier. If the objectSid is used as identifier, this renamed group would just get a renamed name in the same Insight object, if objectSid is used as identifier.
