|
|
* MpNotify main module
|
|
*
|
|
* Mpnotify is an app executed by winlogon to notify network providers
|
|
* of authentication events. Currently this means logon and password change.
|
|
* This functionality is in a separate process to avoid network providers
|
|
* having to handle the asynchronous events that winlogon receives.
|
|
*
|
|
* Winlogon initializes environment variables to describe the event
|
|
* and then executes this process in system context on the winlogon
|
|
* desktop. While this process executes, winlogon handls all screen-saver
|
|
* and logoff notifications. Winlogon will terminate this process if required
|
|
* to respond to events (e.g. remote shutdown).
|
|
*
|
|
* On completion this process signals winlogon by sending a buffer of
|
|
* data to it in a WM_COPYDATA message and then quits.
|
