On a clean install of 9.2.2 I have folders created for the portal but there are no permissions created for the folders.
The DNN Url control displays a warning about not being authorized. This is down to the code in the framework which uses a SP GetFoldersByPermissions. This has an inner join on the Folders and FolderPermission tables. The FolderPermission table is empty for me on a root portal and also any new portals I created.
A work around is to open the folder properties in the file manager and click save. This then creates the permission but only on the folder and not any child folders.
This did work in previous versions of DNN without issue. It would appear the code init the portal folders is not setting the permissions in the table.
