Fixed lastUSN checking improvements
This patch fixes some issues with setting lastUSN attribute and it adds check against the highest user/group USN after enumeration to keep better track of the real highest USN. Optimal solution here would be to schedule a check of rootDSE entry right after the enumeration finishes, but for the moment this is good enough.
