The Permissions tab of the importing dialog allows you to change certain permission settings of the content to be imported.
The "Permissions" tab of the "Import Content" dialog.
Permissions of the imported objects
This section allows you to define which permission settings should be used for the imported content. You can choose between using the permissions from the content package, using default permissions of object types, or specifying customized permissions of your own. For example, if you are publishing objects from a company-internal vault to a publishing vault, different permissions are often used.
Automatic permissions
This section allows you to define settings for automatic permissions of the imported content.
Activate new or changed definitions of automatic permissions
If the content package contains any new or changed definitions of automatic permissions, importing the content package with this option enabled activates all the automatic permissions triggered by the imported definitions in the target vault. Importing the content package with this option unchecked still imports the automatic permission definitions to the target vault, but does not cause any new automatic permissions to be activated.
Ignore the definitions of automatic permissions of the imported objects
When selected, this option makes the importing process bypass the definitions of automatic permissions of all the imported objects in the content package. This way you can choose to preserve the automatic permissions of all the objects in the target vault by leaving out any potential changes to the definitions of automatic permissions from the objects in the imported content package.
