The nobody role means that no user has access — not even admin or maint. Use the nobody role carefully. The nobody role takes precedence over the admin override option on ACLs, so even admins cannot have access.

Do not assign it to specific users. You can use this role in ACLs that control access to resources, such as UI pages, processors, script includes, and records.

Warning: Applying the nobody role may be irreversible if applied to some important system functions.
