Login failed for user . The user is not associated with a trusted SQL Server connection.

I've seen many, many, many, many posts regarding this topic - but none have been able to fully explain nor fix my problem.

I've developed a security solution according toScott Gu's guide and it works great - but only on my local machine running VWD and SQLExp2005. Once I move this application it completely breaks in the productions environment.

Today I managed to get it halfway there. I created a SQL login and changed my web.config to use these credentials - now the web application will come up, but none of my links (that are role based) are displayed - most likely because i'm authenticating as the SQL credentials instead of me.

So I switch it back to windows authenticated, as it is on my laptop, and it breaks again.

Please tell me theres a way to get this working in production and Scott's fantastic tutorial hasn't wasted me 2 weeks of work.

Here's the exact error I get when using Integrated authentication:

Server Error in '/Contracts' Application.

I am not saying it will fix it but it maybe related to your Windows User/Group not having permission in the database when using Windows Authentication. The database permissions are in the new security section in the database in Management Studio. Hope this helps.|||Can you post your Web.config file?sql
