I'm having trouble with my security model, and I was hoping I could find some help.

My ASP.NET app (that uses RS) is going to be running in an intranet environment. So, to develop and test it, I have installed everything locally (i.e., IIS, RS, SQL Server, VS .NET 2003) on my Win2k Server.

In IIS, I have disabled anonymous access so that only Integrated Windows authentication is used. Then in my Web.config file I've set it up to use Windows authentication, as such:

  <appSettings>
    <add key="connectionString" value="database=DatabaseName;Integrated Security=SSPI;server=localhost;Trusted_Connection=true" />
  </appSettings>

  <system.web>
    <authentication mode="Windows" />
    <authorization>
      <deny users="?" />
    </authorization>
    <identity impersonate="true" />
  </system.web>

When I try to access a database (installed on localhost), I get the following error:

System.Data.SqlClient.SqlException: Cannot open database requested in login 'DatabaseName'. Login fails. Login failed for user 'MACHINENAME\ASPNET'.

It's as if it is using the default ASP.NET worker process account (which is not what I want). I need it to authenticate me as my logged in user (which has access to the database).

One more piece of info., if I check the user identity by calling HttpContext.Current.User.Identity.Name, it is correct.

So, my questions are: what am I doing wrong? how do I set up IIS, Web.config, database connection, etc. so that everything is properly authenticated to the logged in user?

Thanks in advance for your help.
