Setting up External Content Type for SQL Server database using SQL Server authentication - SharePoint 2010 Foundation

This post is a follow up on the issues that I have got setting up External Content Type (ECT) on SharePoint 2010 Foundation that was going to connect to remote SQL Server database for information. I cannot use my SharePoint user accounts to access SQL Server.

InfoPath 2013 Preview - URL not valid error when publishing

In InfoPath 2010 there is a problem when you try to publish a Form to a SharePoint site that doesn't have root site collection. You will get an error message "The following url is not valid". It's described here: http://support.microsoft.com/kb/981854 The solution is to create root site collection for the Web application. Same problem is with InfoPath 2013: In my situation I didn't create the root site collection initially, but used "/sites" managed path instead for all site collections. To solve the problem with InfoPath I had to create it. Used a new site template "Project Site". Will get a chance to research that too. :)
