Sid History Domain Trust

Essentially if a user is trying to elevate from a trusted domain the user will add a sid from the trusting domain to that user s sid history.

We can enable sid history to allow that object to authenticate against a list of any previous sids assigned to that object. Depending on whether the existing trust is external or forest based the syntax will.

The domain controller will resolve additional sids to account names from the local database including sids found in sidhistory on a global catalog.
