You can use the following function to get the password expiration date:

HRESULT GetPasswordExpirationDate(LPTSTR lpszPathName, LPSYSTEMTIME lpExpirationDate)
{
    HRESULT hr;
    IADsUser *pUser;
    hr = ADsGetObject(lpszPathName, IID_IADsUser, (void**) &pUser);
    if(SUCCEEDED(hr))
    {
        DATE expirationDate;
        hr = pUser->get_PasswordExpirationDate(&expirationDate);
        if (SUCCEEDED(hr))
            VariantTimeToSystemTime(expirationDate, lpExpirationDate);

        pUser->Release();
    }

    return hr;
}

Where lpszPathNameis a LDAP or WinNT path and lpExpirationDate is a pointer to SYSTEMTIME structure.

Note, that you must include Windows.h, Iads.h and Adshlp.h and link with ADSIid.Lib and ActiveDS.Lib to get it work.

Example usage:

CoInitializeEx(NULL, COINIT_APARTMENTTHREADED);

SYSTEMTIME expirationDate;
HRESULT hr = GetPasswordExpirationDate(_T("WinNT://ComputerName/UserName,user"),
    &expirationDate);

if (SUCCEEDED(hr))
{
    //TODO: do whatever you want with the expirationDate here
}

CoUninitialize();

You may want to use one of the following API calls to retrieve current user and computer/domain names: GetUserName, GetComputerName GetUserNameEx, NetWkstaUserGetInfo

If you need to retrieve password expiration dates for multiple domain users, it might be better to use ADsBuildEnumerator instead of ADsGetObject (see example on MSDN).
