我有一个 ASP.net 应用程序，并且正在使用以下连接字符串：

<configuration>
<connectionStrings>
    <add name="CAF" connectionString="Data Source=pxx-sql2;Initial Catalog=mydb;User ID=DBUser;Password=mypass;Persist Security Info=False;Trusted_Connection=False;"  providerName="System.Data.SqlClient"/>
</connectionStrings>
</configuration>

当我在应用程序中阅读时，一切正常。但是当我写的时候，我收到了这个错误：“对 OLE DB 提供程序 'ADSDSOObject' 的临时访问已被拒绝。您必须通过链接服务器访问此提供程序。”

堆栈跟踪提供：

除了我不认为我在这个项目的任何地方都使用了“ADSDSOObject”。我正在打开与标准 SqlData 句柄的连接。

真正奇怪的是，这是四次中的第四次插入，并且是ExecuteNonQuery我提交事务之前的最后一次（插入时）。

这是完整的功能。

public void Reconcile(HttpRequest req, User u, string assignee)

    SqlConnection conn = new SqlConnection(Config.ConnString);
    conn.Open();

    MyDBLayout bexL = null;

        }
        catch { }
        throw new Exception(e.Message, e);
    }
}

什么可能导致此特定错误？

ADSDSOObject 用于查询 Active Directory。

该错误似乎是在 SQL 服务器中生成的，而不是在您的应用程序中。我怀疑可能存在使用 ADSDSOObject 针对 Active Directory 验证传递的 LoginName (@alteredBy) 或受让人 (@assignedTo) 的约束或触发器。
