## Remarks

- Requires the system administrator server role (server right `manage_licenses`). Denied for a
  vault administrator on a server with a server license.
- On servers that license each vault through M-Files Manage, a vault session of a vault
  administrator gets that vault's license instead; the evaluation fields are then not set.
