Setup

MVC 3 EF 4.1 Code First – Windows 7 Pro 64 Dev machine, Separate Win 7 Pro for host.

I started with a SQLCE4.0 database, and everything worked fine (database initializer created tables, populated, etc…).

Once I got everything working like I wanted, I scripted out my SqlCe DB, created a real SQL 2008 DB, opened the proper ports and enabled TCP connections.

Problem
IF I Change my connection string to point to my intranet server\instance name, with a user I created for this app specifically, it works perfectly running from my dev machine.

IF I publish the app to the server (the web server and sql server are the same), and I try to login to the website (aka access the db), then I get:

CREATE DATABASE permission denied in database ‘master’.

I commented out the DBInitializer setup so nothing should be created upon a db hit. The tables are there already.

If I do Database.SetInitializer(null); then I get a different login error:

I don’t remember exactly but it was something to the affect of LOGIN FAILED FOR IIS APPPOOL\ApplicationPoolIdentity

So I changed the Identity to NETWORK SERVICE and even tried LOCAL SERVICE, both giving the same login failed error.

I tried following this post who says add a SQL user named ‘IIS APPPOOL\MyApplicationName’. SQL Wont let me do that as it has invalid characters … go figure.

Why does it work perfectly over the network accessing the DB from my dev machine, but when I publish to THE SAME machine that hosts the sql and the site, I get permission denied or login failed errors? I’ve scoured the net and tried different things.

EDIT: Here are my connection strings:

<add name="AntripContext" connectionString="Data Source=|DataDirectory|AntripWeb.sdf" providerName="System.Data.SqlServerCe.4.0" />
    <!--<add name="AntripSQL" connectionString="Data Source=.\sqlexpress;Initial Catalog=Antrip;User Id=myuser;Password=mypassword;" providerName="System.Data.SqlClient" />-->
    <add name="AntripWebEntities" connectionString="metadata=res://*/DAL.AntripEntities.csdl|res://*/DAL.AntripEntities.ssdl|res://*/DAL.AntripEntities.msl;provider=System.Data.SqlServerCe.4.0;provider connection string=&quot;Data Source=|DataDirectory|\AntripWeb.sdf&quot;" providerName="System.Data.EntityClient" />
    <!--<add name="AntripWebEntities" connectionString="metadata=res://*/DAL.AntripEntities.csdl|res://*/DAL.AntripEntities.ssdl|res://*/DAL.AntripEntities.msl;provider=System.Data.SqlClient;provider connection string=&quot;Data Source=.\sqlexpress;Initial Catalog=Antrip;User Id=myuser;Password=mypassword;&quot;" providerName="System.Data.EntityClient" />-->

Note: The commented out connection strings are the ones that use the sql 2008 database (that break my published app).

    It sounds to me as if your connection string has Integrated Security=true so that you are connecting to SQL as the user you specify, rather than the SQL user you think you are using?

    But beware, its still trying to create a database: you need to swap the IDatabaseInitializer – I guess it will look for a DB named the same as the entitys to be careful!
