Hi all,
Using C++ .net I have developed a new Gina.dll to replace the one that windows has in order to add support to Biomatrics under windows NT.

At the end of the programming phase i detected that the Logon Scripts were executed,But In login Dialog box last successfully login Username not shown in textbox of 'usernsme'

I have use "ImpersonateLoggedOnUser" for this problem ut prolem not solved.

I have read as many docs as could, but there is something missing i dont see.

//////Code
ImpersonateAndGetUserName(HANDLE hToken, wchar_t* name, int cch) {
    bool result = false;
    if (ImpersonateLoggedOnUser(hToken)) {
        DWORD cchName = cch;
        if (GetUserName(name, &cchName))
             result = true;
        else LCF1(L"GetUserName failed: %d", GetLastError());
        RevertToSelf();
    }
    else LCF1(L"ImpersonateLoggedOnUser failed: %d", GetLastError());

    return result;
}
