我已经安装了这个软件，我公司从LiveDocx购买。所以，我没有修改code，甚至阅读code的能力。我已经根据他们的文档安装了一切，并现场确认工作。我只能在IIS中，文件夹权限和Web.config中更改设置。我们的服务器，他们的软件。

I have installed this software that my company purchased from LiveDocx. So, I don't have ability to modify code or even read the code. I have installed everything according to their documentation and the site is confirmed to work. I can only change settings in IIS, folder permissions, and Web.config. Our server, their software.

现在，我有问题，与住登录到Web服务。在你认为它是SOAP客户端，我已经证实，它的工作原理通过调用供应商的服务器。

Now, I am having issue with staying logged into the webservice. Before you think it is the soap client, I have confirmed that it works by calling the vendor's servers.

在本地，我可以成功调用登录时的Web服务，它工作正常。然而，当我做的后续调用，我得到的请求主体权限失败。。

Locally, I can successfully call the web service during login and it works fine. However, when I make a subsequent call, I get the Request for principal permission failed.

At the request of their technical support, I have added <trust level="Full" /> to the web.config, but that didn't work. Now, they have stopped replying to our emails.

我不是一个ASP.NET开发人员，所以我的知识是在服务器上设置的限制。有人能指出我在正确的方向，为什么这个错误发生，少数地方寻找解决这个问题？

推荐答案

我终于找到了解决办法。此有关权限的错误是有点误导。经过大量的试验和错误，我终于接受了应用程序池用户的权限无关这个问题。这导致我调查的web.config 设置，而这正是我发现这个问题。

I finally found a solution. This error about permissions is a bit misleading. After lots of trial and errors, I finally accepted the Application Pool user's permissions had nothing to do with this problem. Which lead me to investigate the web.config settings and that is where I found the problem.

问题是，所提供的的web.config 文件丢失＆LT;认证＆GT; 标记，并进行必要的设置。这个标签（从我的理解），是使饼干。我希望这有助于与其他人即使不涉及LiveDocx此错误。似乎请求主体权限失败。可用于各种原因引起的，这使得它一个令人沮丧的错误。

The problem was that the supplied web.config file was missing <authentication> tag and the required settings. This tag (from my understanding) is what enables cookies. I hope this helps others with this error even if not related to LiveDocx. Seems Request for principal permission failed. can be caused for various reasons which makes it a frustrating error.
