Manually adding a User and prevent AD sync to overwrite that user?

[ericmoya]

Is there way to configure the synchronization rules and attribute mapping so when user gets a manually created in ServiceNow, the AD synchronization doesn't override the user that was created in ServiceNow

[HIROSHI SATOH]

What about a business rule to cancel the update (cancel with setAbortAction) if the updater (AD user) and creator don't match?

I don't want to cancel the update. I just want it to ignore any users that was manually created within ServiceNow and not in AD
