I have a SharePoint 2007 enterprise edition x64 environment that I am using for WorkFlows. The SharePoint databases are held on a SQL Server 2005. There is also another database on the same sever that holds information such as departments, active users and job titles. I'm trying to get the infoPath forms to retrieve these details and populate them into a drop down box. I want to use stored credentials in the SQL connection from Infopath to the database but I keep getting an error "Login failed for user ??????. The user is not associated with a trusted SQL server connection", see attached. Can anyone tell me how to setup a trusted connection between the infoPath forms on the SharePoint Server and a SQL Server ?
