// Notes: The token's ModifiedId is used to correlate tokens with

// the same SIDs and Privileges. The ModifiedId is changed
|
|
// any time a token is changed. On a server, the privileges
|
|
// are not modified, so the ModifiedId doesn't change typically.
|
|
//
|
|
// The ModifiedId is a LUID, so it's very convenient for
