Module Name:
logon.c
Abstract:
This module contains NetWare credential management code.
Author:
Rita Wong (ritaw) 15-Feb-1993
Revision History:
Yi-Hsin Sung (yihsins) 10-July-1993
Moved all dialog handling to nwdlg.c
Tommy Evans (tommye) 05-05-2000
Merged with code from Anoop (anoopa) to fix problem with
username/password not being stored correctly in the LOGON
list.

Routine Description:
This function is called by Winlogon after the interactive
user has successfully logged on to the local machine. We
are given the username and password, which
are displayed in the NetWare specific logon dialog if
needed.
Arguments:
lpLogonId - Ignored.
lpAuthentInfoType - Supplies a string which if is
L"MSV1_0:Interactive" means that the user has been logged
on by the Microsoft primary authenticator.
lpAuthentInfo - Supplies a pointer to the credentials which
the user was logged on with.
lpPreviousAuthentInfoType - Ignored.
lpPreviousAuthentInfo - Ignored.
lpStationName - Supplies a string which if it is L"WinSta_0"
means that Winlogon logged on the user.
StationHandle - Supplies the handle to the window which to display
our specific dialog.
lpLogonScripts - Receives a pointer to memory allocated by this
routine which contains a MULTI_SZ string of a program to run on
the command line with arguments, e.g. L"myprogram\0arg1\0arg2\0".
This memory must be freed by the caller with LocalFree.
Return Value:
WN_SUCCESS - Successfully saved default credentials.
WN_NOT_SUPPORTED - Primary authenticator is not Microsoft or
is not interactive via Winlogon.
ERROR_FILE_NOT_FOUND - Could not get our own provider DLL handle.

Routine Description:
This routine looks up the SID of a user given the user's logon ID.
It does this by making the current process a logon process and then
call to LSA to get the user SID.
Arguments:
LogonId - Supplies the logon ID of the user to lookup the SID.
UserSidString - Receives a pointer to a buffer allocated by this routine
which contains the user SID in string form. This must be freed with
LocalFree when done.
Return Value:
