User Must Change Password at Next Logon

To force a user to change their password at next logon, set the pwdLastSet attribute to zero (0), as shown in the following code example.

Example Code [Visual Basic]

Dim usr as IADs

Set usr = GetObject("LDAP://CN=Jeff Smith,OU=Sales,DC=Fabrikam,DC=Com")
usr.Put "pwdLastSet", CLng(0)
usr.SetInfo

Example Code [C++]

/***************************************************************************

	SetUserMustChangePassword()

***************************************************************************/

HRESULT SetUserMustChangePassword(LPCWSTR pwszUserADsPath, 
								LPCWSTR pwszUsername, 
								LPCWSTR pwszPassword)
{
	IADs *pUser;
	HRESULT hr;

	hr = ADsOpenObject(pwszUserADsPath,
						pwszUsername,
						pwszPassword,
						ADS_SECURE_AUTHENTICATION,
						IID_IADs,
						(void**)&pUser);

	if(SUCCEEDED(hr))
	{
		VARIANT var;
		VariantInit(&var);
		V_I4(&var) = 0;
		V_VT(&var) = VT_I4;
		hr = pUser->Put(CComBSTR("pwdLastSet"), var);
		hr = pUser->SetInfo();

		VariantClear(&var);
		pUser->Release();
}

	return hr;
}
