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).
