You'll need to translate the AD Long Integer like this and you shouldn't need ActiveDs anymore:

long pwdLastSet = CovertADSLargeIntegerToInt64(oUser.Properties["pwdLastSet"].Value);

public static Int64 ConvertADSLargeIntegerToInt64(object adsLargeInteger)
{
  var highPart = (Int32)adsLargeInteger.GetType().InvokeMember("HighPart", System.Reflection.BindingFlags.GetProperty, null, adsLargeInteger, null);
  var lowPart  = (Int32)adsLargeInteger.GetType().InvokeMember("LowPart",  System.Reflection.BindingFlags.GetProperty, null, adsLargeInteger, null);
  return highPart * ((Int64)UInt32.MaxValue + 1) + lowPart;
}
