SharePoint 和基于表单的身份验证问题 - Office 应用程序不再工作
我们有几个网站在 SharePoint 中使用基于表单的身份验证 (FBA)。其中许多已经运行了几个月，没有出现任何问题。在过去一两周内，我们注意到尝试访问只读 Microsoft Office 文档的用户会出现以下行为（目前仅通过 2007 版 Excel 和 Word 进行验证）。
我们看到的行为如下：
- 文档开始打开
- 在 Office 应用程序中，IE 窗口将打开，并显示 FBA 登录屏幕。左上角还有一个超链接，显示“跳到主要内容”，
- 多次单击“取消”将打开文档。
- 如果您将该站点标识为 IE 受信任站点，则使用 Office 应用程序的登录屏幕，一切都会像以前一样工作（不是我们的大多数网站）
- 非 Office 文件（例如 PDF）不会表现出此行为
- 我们测试过的非 IE 浏览器（FireFox、Chrome）不会表现出此行为。
还有其他人看到这个问题吗？我认为是 Microsoft 发送的更新导致了此问题，因为我们在多个代码尚未更新的网站上看到了该问题。
谢谢
We have several sites that use Forms Based authentication (FBA) within SharePoint. Many of them have been running for months without issues. Within the last week or two we have noticed the following behavior for users trying to access a Read Only Microsoft office document (currently only verified with the 2007 versions of Excel and Word).
The behavior we are seeing exhibited:
- The Document starts to open
- Within the Office application an IE Window opens with the FBA login screen. There is also a Hyperlink in the top left saying Skip to main content
- Clicking cancel several times will open the document
- If you identify the site as an IE Trusted site the login screen with the Office app, everything works as before (not an option for the majority of our sites)
- Non offices files, like PDFs, do not exhibit this behavior
- Non IE Browsers that we have tested (FireFox, Chrome) do not exhibit this behavior.
Is anyone else seeing this issue? I assume it was an update sent from Microsoft that has resulted in this issue, since we are seeing it on multiple sites where the code has not been updated.
Thanks

我们遇到的问题是我们的网络上应用了一个策略文件，导致 Vista/Win 7 的 UAC 提示被禁用。发生这种情况时，IE 浏览器的保护模式将被关闭，这导致了我们看到的问题。
The issue we ran into is there was a policy file applied on our network that caused the UAC prompt to be disabled for Vista/Win 7. When this happens, protected mode gets turned off for the IE browsers, which caused the issues we were seeing.
如果您希望 Office 集成在表单身份验证下工作，您应该执行以下操作：
如果在打开的 Office 文档中仍然看到嵌入的登录屏幕，请在客户端计算机（如果是 Windows 7）上尝试以下操作：
If you want Office integration to work under forms authentication you should do the following:
If you still see a login screen embedded in Office documents that you open, try the following on the client computer (if Windows 7):
