Creating a service or customer admin
From Advanced Mode > Portal Management > Admin Users, select "Create Admin User". This brings up the following dialog.
You may select the admin type, as well as the authentication scheme for the admin.
Locally-authenticated admins require an initial password, but checking the box at the bottom of the dialog forces the admin user to enter a new password when they log in.
Externally-authenticated admins use the global (service admin) or customer tenant (customer admin) IdP that has been configured.
Activating/Deactivating/Deleting an Admin
From Advanced Mode > Portal Management > Admin Users, you may deactivate or activate an admin user. Deactivating the admin prevents the admin from logging in without deleting the account.
You may also delete an admin from this menu. Deletion completely removes the admin from the system.
