sspi impersonation

[giuliohome]

I'm trying to use an access token from node-expose-sspi to impersonate the authenticated user as described in this scenario.

[giuliohome]

My conclusion.
I have compared C# impersonation with Node.js impersonation. The problem is the return from the Napi call to Node.js. The pure C++ impersonation - i.e. the impersonateLoggedOnUser with a token from a LogonUserW - is successful exactly like C#, that is correctly wrapping a C++ call through DllImport of InteropServices. If I write a file from C++ the owner of the file written is the impersonated user. The problem is that when the control is returned to Node.JS after the wrapped Napi call (on the opposite of what happens with C# interop) the impersonation is lost.

Again I doubt that this is a specific problem of my debug environment details, I rather think that the reply received from stackoverflow forum about it has been wrong.
