Question

I use asp.net 4 and c#. I’m testing a website on my local computer.

Her my connection string:

<connectionStrings>
    <add name="CmsConnectionString" connectionString="Data Source=.; Initial Catalog=CmsSiteNameExtension; Integrated Security=SSPI"/>
    <add name="CmsConnectionStringEntityDataModel" connectionString="Metadata=res://*/;          provider=System.Data.SqlClient;provider connection string=&quot;&#xA;          Data Source=.;Initial Catalog=CmsSiteNameExtension;Integrated Security=True;MultipleActiveResultSets=True&quot;" providerName="System.Data.EntityClient"/>
</connectionStrings>

I receive this error when try to run locally my web app.

Cannot open database "CmsSiteNameExtension" requested by the login. The login failed.
Login failed for user 'WIN-S6G3M6TMQLT\XXX'

Any idea what is wrong and how to solve it?

Answer 1

use Integrated Security=True ( replace Integrated Security=SSPI with Integrated Security=True), i hope it will work.
