ASP.NET Web服务无法与IIS7中的数据库连接

Question

当我尝试在IIS7上发布asp.net Web服务应用程序时，在使用Visual Studio进行调试时，我的应用程序可以完美运行。 但是，当我尝试通过在浏览器上键入以下内容来从IIS访问IIS的Web服务时： http://localhost:port/Service1.asmx并单击该方法，然后单击“调用”，这会给我这个错误：

System.Data.SqlClient.SqlException: The SELECT permission was denied on the object 'Marimi', database 'eMagazin', schema 'dbo'.
   at System.Data.SqlClient.SqlConnection.OnError(SqlException exception, Boolean breakConnection, Action`1 wrapCloseInAction)
   at System.Data.SqlClient.SqlInternalConnection.OnError(SqlException exception, Boolean breakConnection, Action`1 wrapCloseInAction)
   at System.Data.SqlClient.TdsParser.ThrowExceptionAndWarning(TdsParserStateObject stateObj, Boolean callerHasConnectionLock, Boolean asyncClose)
   at System.Data.SqlClient.TdsParser.TryRun(RunBehavior runBehavior, SqlCommand cmdHandler, SqlDataReader dataStream, BulkCopySimpleResultSet bulkCopyHandler, TdsParserStateObject stateObj, Boolean& dataReady)
   at System.Data.SqlClient.SqlDataReader.TryConsumeMetaData()
   at System.Data.SqlClient.SqlDataReader.get_MetaData()
   at System.Data.SqlClient.SqlCommand.FinishExecuteReader(SqlDataReader ds, RunBehavior runBehavior, String resetOptionsString)
   at System.Data.SqlClient.SqlCommand.RunExecuteReaderTds(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream, Boolean async, Int32 timeout, Task& task, Boolean asyncWrite)

   at System.Data.SqlClient.SqlCommand.ExecuteReader()
   at WebService.Service1.GetMarime() in C:\Users\Eduard\Desktop\MaG_beta01\MaG\WebService\Service1.asmx.cs:line 741

我在web.Config中与数据库的连接是：

<connectionStrings>
    <add name="connection" connectionString="Data Source=EDUARD-PC\EDD;Initial Catalog=eMag; Integrated Security=True;" providerName="System.Data.SqlClient"/>
  </connectionStrings>

我将ASP.NET v4.0 Classic用作应用程序池

我已经在Google上搜索了解决方案，但没有发现任何帮助。...预先谢谢大家...

“应用程序池标识”对您的数据库没有权限：要么不使用集成安全性，要么为拥有数据库权限的appool创建专用用户。
