App Portal 2020 R1
When configuring App Portal, you will need to specify which users and groups can view and modify the App Portal catalog. This secures the App Portal site catalogs to the listed groups and users.
You configure catalog security on the Catalog Security View, which is opened by selecting Catalog Security under Site Management on the Admin tab.
Catalog Security View
On each of the tabs of the Catalog Security View, you can view and edit the security settings for existing users and groups for that particular role.
However, you assign initial permissions to a user or group for all roles on the Catalog Security Add User/Group dialog box that opens when you click Add User/Group on the Catalog Security View.
To enable a user to view the non-administrative tabs of the App Portal / App Broker interface even when the end-user facing site is disabled (such as when using App Broker), select the Access Non Admin Tabs When Site Is Disabled option. For more information, see Providing Access to Non-Admin Tabs When App Portal Site is Disabled.
