Running spawned worker thread as impersonated user

you need to pass the creditials of the current thread to the new created
thread.
class foo()
{
private WindowsIdentity mThreadIdentity = null;
[DllImport("adva pi32")] static extern bool RevertToSelf();

public void StartThread()
{
// setup thread

ThreadStart ts = new ThreadStart(Run Report);
Thread t = new Thread(ts);
mThreadIdentity = WindowsIdentity .GetCurrent();

// drop any impersonation

RevertToSelf();

// start thread

t.Start();

// restore thread identity

mThreadIdentity .Impersonate();

}

private void RunReport()
{
mThreadIdentity .Impersonate();
// do whatever
}
}

I have an ASP.NET web service whose Web.Config is set to use impersonation

<authenticati on mode="Windows" />
<identity impersonate="tr ue" />
Within a Web Method, I want to use Multi-threading to spawn off an
asynchronous process, as it takes quite long to return. How could I get
the
worker thread to runas the same impersonated user on ASP.NET?

Dim worker As System.Threadin g.Thread = New
System.Threadin g.Thread(Addres sOf reportManager.R unReport)
worker.Start()

my reportManager.R unReport is in a *different* class from the web method that
spawn it off. Hence, it won't be able to reference mThreadIdentity .

In addition, could you clarify the definition of [DllImport("adva pi32")]
static extern bool RevertToSelf(); .e.g. what is the EntryPoint?
