The cache stores FreeRADIUS control attributes such as `SSHA-Password`; it does not store plaintext passwords. Frappe stores only verifier material in `Stored Credential Verifier`, not plaintext device passwords. When Frappe is unreachable, the module can continue authorizing previously cached long-lived IoT credentials. + +### Credential provisioning + +Approved devices can be owned by a Frappe `User`. A System Manager or the owning user can provision RADIUS credentials in two ways: + +- Device credential: a username/password or generated deployment key attached to one `DM Device`. This is the preferred mode for long-lived IoT and lab equipment because the offline FreeRADIUS cache can safely bind the verifier to a specific device decision. +- Owner shared credential: a username/password or generated deployment key attached to the owning Frappe user through `DM Radius Credential`. This can be used across devices owned by that user, while the device MAC still drives authorization, VLAN selection, and audit records. + +Provisioning actions hash the submitted password/key immediately using an SSHA verifier for FreeRADIUS. Generated deployment keys are returned once for installation on the device and are never stored in plaintext. + +#### FreeRADIUS Integration Details + +For detailed FreeRADIUS configuration, see: +- [radius_client/CONFIGURATION.md](radius_client/CONFIGURATION.md) - Complete FreeRADIUS setup guide +- [radius_client/README.md](radius_client/README.md) - Standalone client installation + +The module reads common request attributes such as `Calling-Station-Id`, `User-Name`, `NAS-Identifier`, `NAS-IP-Address`, and SSID attributes, then writes `DM Radius Auth Event`, `DM Access Decision`, and `DM Device Audit Event` records when Frappe is reachable. + +### UniFi live network views + +Device Manager can expose UniFi controller state through read-only Virtual DocTypes: + +- `DM UniFi Client` +- `DM UniFi Network Device` +- `DM UniFi Network` + +Configure `DM UniFi Settings` with the UniFi OS or self-hosted Network Controller URL, site ID, TLS behavior, and either an API token or a least-privilege local UniFi account. The virtual DocTypes call UniFi live and do not persist controller state in the Frappe database. This is intended for operator visibility and cross-checking Device Manager records against current network state while keeping UniFi as the source of truth for volatile client/AP/network telemetry. + +`DM UniFi Settings` also provides operator actions for the core workflows: + +- Sync UniFi networks into durable `DM Network Segment` mappings. +- Reconcile registered devices against live UniFi clients and update current IP, SSID, client ID, and network segment. +- Import unmatched UniFi clients as authorized `DM Device` records, because a client already visible in UniFi is an observed network asset rather than a self-service registration request. +- Convert older UniFi-created `DM Device Registration` records into `DM Device` records while preserving the registration as historical approval/audit context. + +`DM Device Registration` remains the intake object for self-service requests and proposed device onboarding before a device is accepted into the managed inventory. UniFi telemetry should populate `DM Device` directly; operators can then change lifecycle status, authorization status, or network segment if the imported device needs quarantine or reassignment. ###
