## Remarks

- Requires the system administrator server role (server right `manage_logins`).
- `srvroles` is always written; send the complete set (including `can_log_in` to keep the login
  enabled). The other fields are written only when `change_password` or `update_other_fields`
  is true.
- Changing the license type fails if no license of that type is available.
- On servers that use vault login accounts, a login that is not a system administrator can only
  be disabled or set to no license here.
- `update_client_id` and `client_id` are ignored by this method.
- By default, the linked user accounts in the online vaults are refreshed after a change.
