我在 Active Directory 中创建了域用户“jsmith”，并将该域帐户添加为 Dynamics CRM 中的用户。我的目标是使用组织的 PrivUserGroup 中的服务帐户执行代码，同时模拟“jsmith”。我通过传递一个 CrmConnection 实例来实例化 CrmDataContext。在调用 CrmConnection 的构造函数时，我在应用程序配置文件中将连接字符串的名称传递给它，然后将 ImpersonatedUser 属性设置为“jsmith”的系统用户 ID。需要注意的一点是，我正在使用控制台应用程序来运行它。在下面查看我的代码：
app.config 中的连接字符串：
<add name="Crm" connectionString="Authentication Type=AD; Server=http://dev01/myorg; User ID=myorgdomain\sv-crm; Password=password123" />
CrmDataContext 和 GetEntities 代码：
var connection = new CrmConnection("Crm");
connection.ImpersonatedUser = Guid.Parse("1937F45C-8EB4-E011-8FE4-005056887B79");
var crm = new CrmDataContext(connection);
var contacts = crm.GetEntities("contacts")
if(contacts.Count() > 0) //the call to Count() is where the error gets thrown. Invalid user auth.
//do something
尝试使用与我在运行测试时登录的 AD 域帐户绑定的系统用户 ID 进行模拟时，我没有任何问题。我得到的结果很好，所以我知道用于执行代码的服务帐户没有问题。我什至将“jsmith”分配给了同一个业务部门，并让他担任与我相同的角色（即系统管理员），但我仍然得到无效的用户身份验证。我可能会错过什么。以下是服务器上跟踪文件中的错误信息。在下面的跟踪信息中，确实突出的是第一行：“[2011-07-22 18:14:08.0] Process: w3wp |Organization:f827deb3-c6cc-df11-bc07-005056887b79 |Thread: 6 |类别：异常 |用户：822138f1-c574-e011-9dca-005056887b79|级别：错误 | CrmException..ctor*”。正在显示的用户 id 是我的系统用户 id。它似乎会显示连接字符串中的服务帐户的 id 或被模拟的 id 'jblow'。任何想法都会不胜感激。

更新 7/25：我决定通过使用 CrmDataContext 进行调用来执行测试，其中 CrmConnection.ImpersonatedUser 设置为 jsmith id。然后，我使用老式方法进行了另一个调用（完全相同的查询），您在其中构建 QueryExpression 并将其传递到 CrmService，其中 CrmAuthenticationToken 的 CallerId 属性设置为 jsmith 的 id。使用 CrmDataContext 失败并出现“无效的用户身份验证”错误，但使用 CrmService 和 QueryExpression 的另一个调用运行良好。我使用 fiddler 查看每个调用的原始 http 请求。两个调用的原始请求完全相同，除了一件事......请求的授权标头中的协商令牌。我打了两个电话，一个接一个，在我的控制台应用程序中，它们会产生不同的协商令牌。这一定是问题，虽然我不知道如何解决。似乎这是高级开发人员扩展中的一个错误。以下是两者的原始http。
