How to find current users active directory group in C++?

Question

How would I go about querying what active directory group the currently logged in user belongs to? Below I add the example code which is similar to what I want. In that code they use "WinNT" method to work on it. But I want to use Ldap format like this -> hr = ADsOpenObject(L"LDAP://10.20.214.74/OU=Vimal,DC=test,DC=local". Can anyone please help me to find the solution? Thanks in Advance.

IADsGroup *pGroup = NULL;
HRESULT hr = S_OK;
LPWSTR adsPath = L"WinNT://Fabrikam/Administrators";
BSTR bstr = NULL;

hr = ADsGetObject(adsPath, IID_IADsGroup, (void**)&pGroup);

if(FAILED(hr))
{
goto Cleanup;
}

hr = pGroup->get_Description(&bstr);
if(FAILED(hr))
{
goto Cleanup;
}

printf("Description: %S\n",bstr);
SysFreeString(bstr);

VARIANT_BOOL inG=false;
hr = pGroup->IsMember(CComBSTR("WinNT://Microsoft/SecUser"), &inG);

if (inG ) 
{
printf("already in the group.\n");
}
else 
{
hr = pGroup->Add(CComBSTR("WinNT://Microsoft/SecUser"));
if(FAILED(hr))
{
    goto Cleanup;
}

printf("user added.\n");
}

Cleanup:
if(pGroup)
{
pGroup->Release();
}
if(bstr)
{
SysFreeString(bstr);
}

return hr;
