ASP.NET web service does not connect with database

问题:

When I try to publish my asp.net web service application on IIS7, my application works perfect when debugging with Visual Studio. But, when I try to access my webservice from IIS by typing on browser: http://localhost:port/Service1.asmx and click on the method and then click "Invoke" it gives me this error:

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)

My Connection to database in web.Config is :

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

and I use as Application Pool the ASP.NET v4.0 Classic

I've searched for the solutions on google but I haven't found anything helpful.... Thank you all in advance...

The Application Pool Identity has no permissions on your database: either do not use integrated security, or create a dedicated user for the appool who has database permissions.
