The warning "home storage not writable" when executing occ files:scan is to be expected with guest users.
The Shared with Guests Filter

This filter makes it easy for sharers to view and remove their shares with a guest, which also removes their responsibility for guests. When all of a guest’s shares are removed, the guest is then disabled and can no longer login.

Standard User

  • Is a regular user (from LDAP, ownCloud user backend, or another backend).

  • Has personal space. Permissions are granted by the administrator.

  • Shared space: Permissions as granted by sharer.

  • Apps: All enabled, might be restricted by group membership.

Federated User

  • Is not an internal user.

  • Can trust a federated system.

  • Has access to shared space through users on the considered ownCloud system.

  • Can share data with the considered system (accept-/rejectable).

ownCloud Group Administrator

ownCloud Administrator

  • Is a regular user (from LDAP, ownCloud user backend, or another backend).

  • Can configure ownCloud features via the UI, such as sharing settings, app-specific configurations, and external storages for users.

  • Can manage users, such as adding and removing, enabling and disabling, quota and group management.

  • Can restrict app usage to groups, where applicable.

  • Configurable access to log files.

  • Mounting of external shares and local shares (of external filesystems) is disabled by default.

System Administrator

  • Is not an ownCloud user.

  • Has access to ownCloud code (e.g., config.php and apps folders) and command-line tool (occ occ).

  • Configures and maintains the ownCloud environment (PHP, Webserver, DB, Storage, Redis, Firewall, Cron, and LDAP, etc.).

  • Can manage users and groups, such as via occ.

  • Has access to the master key when storage encryption is used.

Auditor

  • Is not an ownCloud user.

  • Conducts usage and compliance audits in enterprise scenarios.

  • App logs (especially Auditlog) can be separated from ownCloud log. This separates the Auditor and Sysadmin roles. An audit.log file can be enabled, which the Sysadmin can’t access.

  • Best practice: parse separated log to an external analyzing tool.
