// HEINOUS SSPI HACK here: AcquireCredentialsHandle is called with the package
|

|
|
// name ("Digest") as the package identifier. When AcquireCredentialsHandle returns
|
||
|
|
// 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.
