I have problem with Business Data Connectivity, when I try to create new external content type in SharePoint Designer - I "Add Connection" then I choose SQL Server I fill Database Server and Name and I can't connect I see "Login failed for user" In Evet Log I have Critical error Event ID 8080.
The BDC service is working and user have perrmision to SQL database.
I use SharePoint Foundation and SharePoint Designer.
