誤差時，我沒有使用ASP應用程序提供商「專案OLE DB提供程序訪問」

Question

我有一個ASP.net應用程序，我使用了下面的連接字符串：

<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> 

當我閱讀應用程序時，一切正常。但是當我寫的時候，我得到這個錯誤：「對OLE DB提供程序」ADSDSOObject「的臨時訪問已被拒絕，您必須通過鏈接服務器訪問此提供程序。」

提供的堆棧跟蹤：

[SqlException (0x80131904): Ad hoc access to OLE DB provider 'ADSDSOObject' has been denied. You must access this provider through a linked server.]

除了我不認爲我使用的是「ADSDSOObject」在這個項目中的任何地方。我打開了一個標準的SqlData句柄的連接。

真奇怪的是，這是第四次插入，這是我在提交事務之前的最後一個ExecuteNonQuery（插入）。

這是整個功能。

public void Reconcile(HttpRequest req, User u, string assignee) 
{ 
    SqlConnection conn = new SqlConnection(Config.ConnString); 
    conn.Open(); 
    SqlTransaction transaction = conn.BeginTransaction("UpdateMyDB");

      cmd.Parameters.AddWithValue("@bexMasterID", bexForm); 
     else 
      cmd.Parameters.AddWithValue("@bexMasterID", DBNull.Value); 
     cmd.ExecuteNonQuery(); 

     // Remove old detail 
     cmd.Parameters.Clear(); 
     cmd.CommandText = @"delete from MyDB_detail where MyDBID = @MyDBID";

     FixNotes(MyDBID, req, cmd); 

     AddDetail(MyDBID, MyDBL, req, cmd);

     cmd.Parameters.Clear();

     transaction.Commit(); 
    } 
    catch (System.Exception e) 
    { 
     try

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

這可能是導致此特定錯誤？

Answer 1

ADSDSOObject用於查詢Active Directory。

該錯誤似乎是在SQL服務器中生成的，而不是在您的應用程序中生成的。 我懷疑可能有一個約束或觸發器使用ADSDSOObject對Active Directory驗證傳遞的LoginName（@alteredBy）或受讓人（@assignedTo）。
