MVC3 Connection String Issue

Posted on 2011-03-22

Last Modified: 2012-05-11
I have created a web application using MVC3 and .NET4 and SQL Server 2008. Everything works good if i run it locally on my machine. But i try to connect to our development database (SQL Server 2008 with Compatibility set to 2008) i keep getting error :
If i make my connection string as
<add name="OFREntities" connectionString="metadata=res://*/OFR.csdl|res://*/OFR.ssdl|res://*/OFR.msl;provider=System.Data.SqlClient;provider connection string=&quot;Integrated Security=true;Initial Catalog=MA;Data Source=DEV50SQL;Persist Security Info=True;User ID=MASTool_User;Password=admin;MultipleActiveResultSets=True&quot;" providerName="System.Data.EntityClient" />
Error i get :
Login failed. The login is from an untrusted domain and cannot be used with Windows authentication.

If i make Integrated Security=false in above connection string i get following error :

System.InvalidOperationException: There is already an open DataReader associated with this Command which must be closed first.

Im confused, Can anyone help me out with this?

Ok, basics first. Is your Dev SQL Server on the same domain as your local machine? You also shouldn't have both Integrated Security and Username/password in the connection string, you should be using one or the other.

No, the dev SQL server is on different domain

Then that's your problem. You won't be able to authenticate against a SQL Server on a different domain unless there is a shared trust between them. And even then you will need to add your domain user as a valid login on the remote SQL Server.

First off, remove "Integrated Security" from the connection string and see if it is able to authenticate using the userid and password.

got the resolution, there was an issue with HP Ployserv clustring. Entity Frame work and Polyserve do not go well together. We had 3 level of aliasing and had to go with 1 level alias and it solved the issue.
