// to the caller PCredHandle->dwLower is set by security.dll to be the index of
// the package returned. EnumerateSecurityPackages. This is how SSPI resolves the
// correct provider dll when subsequent calls are made through the dispatch table
// (PSecurityFunctionTale). Any credential *or* context handle handed out by the
// package must have the dwLower member set to this index so that subsequent calls
// can resolve the dll from the handle.
