Feststellen, ob Benutzer kein Passwort hat

[Remko]

Assarbad shared this with me today:

Code:

bool IsPasswordRequired(wchar_t * Username)
{
  HANDLE hToken = NULL;
  if(LogonUser(Username, NULL, L"", 2, 0, &hToken)) CloseHandle(hToken);
  DWORD dwErr = GetLastError();
  return (ERROR_PASSWORD_RESTRICTION  != dwErr) && (ERROR_LOGON_FAILURE  == dwErr) && (1267 == dwErr);
}
