Wrong date interpretation on user account
Bug reports
When analyzing users under SAM\Domains\Account\Users, the account expiration date is found in offset 32-39.
The value 7FFFFFFFFFFFFFFF or 0 will mean that the account never expires (ref https://msdn.microsoft.com/en-us/library/ms675098(v=vs.85).aspx).
In Fred, the value 7FFFFFFFFFFFFFFF is interpreted as 1975/01/22 22:55:33
I can provide a SAM file for testing if you like.
