Question

我正在尝试使用LsaLogonUser创建交互式登录会话，但它始终返回STATUS_INVALID_INFO_CLASS（0xc0000003）。从我在网上搜索中发现的内容来看，KERB_INTERACTIVE_LOGON结构的内存布局很棘手，但我很确定我已经做到了。

我也尝试过使用MSV1.0而不是Kerberos，其中MSV1_0_INTERACTIVE_LOGON用于身份验证结构，MSV1_0_PACKAGE_NAME用作包名，但是STATUS_BAD_VALIDATION_CLASS（0xc00000a7）失败。

谁能告诉我这里做错了什么？这是代码，大部分错误处理都被剥离了。显然，这不是生产质量;我只是想找一份工作样本。

你把其中一个参数搞砸到了LsaLogonUser（）;而不是&authInfo，你应该只传递authInfo。发生在所有人身上:)）

如何正确调用LsaLogonUser进行交互式登录？
