After installing SSIS 2014, it is the time to deal with the permissions.
When dealing with the DCOM Config (control Panel->Administrative Tools-> Component Services), you want to set up the permissions for Microsoft SQL Server Integration Services 12.0 as you can see on the picture below:
You right click on it, and on the first tab, called General, you see the option Authentication Level. The default is Call, but there are other options, as you can see on the picture.
Where is the documentation for this? What does each option really mean?
