	  Look at a user on a real NT4 PDC with usrmgr, press
	  'ok'. Then you will see that fields_present is set to
	  0x08f827fa. Look at the user immediately after that again,
	  and you will see that 0x00fffff is returned. This solves
	  the problem that you get access denied after having looked
	  at the user.
