Why directory_services_config is rated Low
This tool retrieves directory services configuration (Active Directory / LDAP settings). It performs a read-only query of existing system configuration without creating, modifying, deleting, or executing any operations. The blast radius of misconfiguration is minimal since the tool only exposes what directory services are currently configured, not the ability to change them or authenticate via those services.
From the tool's definition Tool name and description: 'Get directory services configuration' - the verb 'Get' and action 'retrieve configuration' indicates a query operation with no modifications or side effects.
Attacks that exploit this kind of access
The rule that runs directory_services_config safely

directory_services_config is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Truenas, apply this rule, and every directory_services_config call is checked against it from then on.
