windows登陆：gina。如何在自己的gina中的WlxLoggedOutSAS，用LogonUser登陆。（老是死机！！！！？？？）

[xyz_mw]

1。写了个gina，如果全部转调用 msgnia的wlx函数，ok
2。我用msdn上的类似代码替换了WlxLoggedOutSAS，程序调WlxActiveUserShell失败
3。我用msdn上的类似代码替换了WlxLoggedOutSAS，WlxActiveUserShell，进入桌面之后，马上crash掉！！！！！
哪位高人做过gina，指点一下！谢谢

自己钻研把！

那你的代码是MSDN上的这一段吗？
int WINAPI WlxLoggedOutSAS (
PVOID pWlxContext,
DWORD dwSasType,
PLUID pAuthenticationId,
PSID pLogonSid,
PDWORD pdwOptions,
PHANDLE phToken,
PWLX_MPR_NOTIFY_INFO pMprNotifyInfo,
PVOID * pProfile)
{

PGINA_CONTEXT pgContext = (PGINA_CONTEXT) pWlxContext;
TOKEN_STATISTICS userStats;
DWORD cbStats;

if (!phToken)
return WLX_SAS_ACTION_NONE;

// Attempt to log on the user.
// Assignments for pwszUser, pwszDomain, and pwszPassword
// handled elsewhere.
if (!LogonUser(pwszUser,
pwszDomain,
pwszPassword,
LOGON32_LOGON_UNLOCK,
LOGON32_PROVIDER_DEFAULT,
phToken))
return WLX_SAS_ACTION_NONE;

// Check the user token.
if (!(*phToken)) {
return WLX_SAS_ACTION_NONE;
}

// Save the user token in the GINA context
pgContext->UserToken =*phToken;

// Pass back null profile and options.
*pdwOptions = 0;
*pProfile = NULL;

// Get the authenticationid from the user token.
if (!GetTokenInformation(*phToken,
TokenStatistics,
(PVOID) &userStats,
sizeof(TOKEN_STATISTICS),
&cbStats))
{
return WLX_SAS_ACTION_NONE;
}
else
{
*pAuthenticationId = userStats.AuthenticationId;
}

// Pass back multiple provider information.
pMprNotifyInfo->pszUserName = DupString(pwszUser);
pMprNotifyInfo->pszDomain = DupString(pwszDomain);
pMprNotifyInfo->pszPassword = DupString(pwszPassword);
pMprNotifyInfo->pszOldPassword = NULL;

return WLX_SAS_ACTION_LOGON;
}

PWSTR DupString(PWSTR pszString)
{
DWORD cbString;
PWSTR pszNewString;

cbString = (wcslen(pszString) + 1) * sizeof(WCHAR);
pszNewString = LocalAlloc(LMEM_FIXED, cbString);
if (pszNewString)
{
CopyMemory(pszNewString, pszString, cbString);
}
return(pszNewString);
}

帮楼主顶，关注！

当然是这一段，这两端代码更本不能用的。今天网上看了pgina的资料，写pgina的那些人多没调试出来，LongonUser只是用来验证用户，然后写注册表自动登陆。最终还是要调用的msgina的WlxLoggedOutSAS 完事。看来，我也只能这样了。msdn害人不浅，浪费我这么多时间，kao

你的gina必须有msgnia的所有导出函数。
简而言之，就是即使你替换一个函数，也要把其他的都导向msgnia的wlx函数。

to:wangk(倒之) ,其它我当然多导向到msgnia。
