## Remarks

**For M-Files components only.** Used by M-Files Admin. Applications should not call it.
- Requires the system administrator server role (server right `edit_web_access_settings`).
  Denied for other callers.
- A missing prerequisite fails the call with an error that names it; on success
  `requirements_met` is true.
