freeradius-server

FreeRADIUS server implementation for running AAA (Authentication, Authorization, Accounting) for network access, typically used with 802.1X, VPN, and other RADIUS-capable clients. Provides pluggable modules (e.g., SQL/LDAP/files) and supports standard RADIUS protocols.

RADIUS traffic security depends on deployment choices and configuration (e.g., whether to use TLS-capable variants like RadSec, and how secrets/config are stored). Stronger protections require careful key/secret management, least-privilege for backend access, and hardening of network exposure and logging.

Best When

You need standards-based RADIUS AAA in a self-hosted/on-prem environment with configurable backends and network-device integration.

Avoid When

You cannot operate and secure a network-facing service, or you need a turnkey managed AAA offering without tuning/maintenance.

Use Cases

  • 802.1X network access (Wi-Fi/Ethernet) authentication
  • VPN authentication/authorization via RADIUS
  • Centralized AAA with configurable realms and policies
  • Accounting for access session auditing/billing integration
  • Integration with identity stores (e.g., SQL/LDAP) for user credentials and group/policy lookup

Not For

  • Browser-based user authentication workflows (no web app/API focus)
  • Applications needing modern HTTP/REST APIs as the primary interface
  • Use cases requiring built-in hosted SaaS managed reliability (this is self-hosted software)

Authentication

Methods: RADIUS (server-side) Shared secret between RADIUS client and server (per client)
OAuth: No Scopes: No

Authentication to the server is implicit via the RADIUS protocol shared secret configured for each RADIUS client; user authentication is delegated to configured FreeRADIUS modules/backends.

Pricing

Free tier: No
Requires CC: No

Open-source/self-hosted; costs are infrastructure and operations (hardware, hosting, maintenance, supporting dependencies).

Known Gotchas

  • Configuration-driven behavior: success depends heavily on correct realm/module/policy configuration rather than simple API calls.
  • Testing and troubleshooting are protocol/crypto/policy sensitive (RADIUS ports, firewalling, shared secrets, and module settings).
  • As a network server, automation/agents must manage service lifecycle and validate logs/config changes safely.
