WlxNetworkProviderLoad function

[The WlxNetworkProviderLoad function is no longer available for use as of Windows Server 2008 and Windows Vista.]

The WlxNetworkProviderLoad function must be implemented by a replacement GINA DLL. Winlogon calls this function to collect valid authentication and identification information.

Note   GINA DLLs are ignored in Windows Vista.


BOOL WlxNetworkProviderLoad(
  _In_  PVOID                pWlxContext,
  _Out_ PWLX_MPR_NOTIFY_INFO pNprNotifyInfo


pWlxContext [in]

Pointer to the GINA context associated with this window station. The GINA returns this context value when Winlogon calls WlxInitialize for this station.

pNprNotifyInfo [out]

Points to an WLX_MPR_NOTIFY_INFO structure that contains domain, user name, and password information for the user. Winlogon will use this information to provide identification and authentication information to network providers.

The GINA is not required to return password information. Any NULL fields within the structure will be ignored by Winlogon. Use LocalAlloc to allocate each string; Winlogon will free them when they are no longer needed.
