nauthilus_misc

The nauthilus_misc module exposes small helper functions for Lua scripts.

local misc = require("nauthilus_misc")

misc.scoped_ip

Returns a normalized identifier for an IP address according to configured scoping rules.

Configuration precedence

• for ctx = "lua_generic":
  • auth.backends.lua.backend.default.ip_scoping_v6_cidr
  • auth.backends.lua.backend.default.ip_scoping_v4_cidr
• for ctx = "rwp" and ctx = "tolerations":
  • the brute-force scoping settings under auth.controls.brute_force.ip_scoping

Example configuration

auth:
  backends:
    lua:
      backend:
        default:
          ip_scoping_v6_cidr: 64
          ip_scoping_v4_cidr: 24

Example usage

local misc = require("nauthilus_misc")

local scoped = misc.scoped_ip("lua_generic", request.client_ip)

When no CIDR is configured for the chosen context and IP version, the original IP is returned unchanged.
