Authentik is the likely destination and the page had Authelia and lldap wired in at every level, so the seam goes in now: the panels and every endpoint action route off one conf value, and a stack that cannot be driven yet says so rather than drawing controls with nothing behind.

// ═══════════════════════════════════════════════════════════════════════════════════════════════
|
|
// PURPOSE
|
|
// Auth stack endpoint. The single URL behind the auth tab, covering all three services it
|
|
// manages: Nginx Proxy Manager proxy hosts and certificates, lldap users and groups, and
|
|
// Authelia access rules.
|
|
//
|
|
// OPERATIONAL MODEL
|
|
// Read and write share one URL, split on HTTP method. GET serves the five read actions and
|
|
// is always safe. POST carries an action naming exactly one library call. Anything that is
|
|
// neither GET nor POST is refused with 405 before a parameter is read.
|
|
//
|
|
// Three services, one endpoint, because they are one subject. The auth stack is HOST1's
|
|
// source of truth for identity, and a change in one service usually accompanies a change in
|
|
// another — a new lldap user is only useful once an Authelia rule and an NPM host exist for
|
|
// it. Splitting them into three endpoints would split one page's work across three files
|
|
// with three copies of the same dispatch.
|
|
//
|
|
// DESIGN PRINCIPLES
|
|
// Both dispatches are closed match expressions.
|
|
// Every action maps to one named library call, and an unrecognised action falls to a
|
|
// default arm that returns an error. No part of the request is ever used to construct a
|
|
// function name, so the action list is the complete set of things this endpoint can do.
|
|
//
|
|
// The endpoint holds no auth logic of its own.
|
|
// Token acquisition, API dialects, config parsing and the Authelia container restart
|
|
// all live in include/auth.php. This file is dispatch and nothing else, which is what
|
|
// keeps the credential handling in one auditable place.
|
|
//
|
|
// Structured payloads arrive as JSON in a form field.
|
|
// Proxy definitions and rule sets are nested, so they are passed as encoded JSON rather
|
|
// than flattened into form keys — a rule set does not survive form encoding intact.
|
|
//
|
|
// OPERATIONAL SAFEGUARDS
|
|
// Wrong method is refused with a status code, not just a body, so a mistaken caller fails
|
|
// visibly rather than parsing an error object as data.
|
|
//
|
|
// Every parameter is optional and typed at the call site.
|
|
// (int) casts on ids, ?? '' on strings, ?? '0' === '1' on flags. A malformed POST
|
|
// reaches the library as zeros and empty strings — which the library rejects — rather
|
|
// than raising undefined-index warnings into the JSON body and corrupting the response.
|
|
//
|
|
// Malformed JSON degrades to an empty structure.
|
|
// json_decode with ?: [] on both data and rules. A truncated payload becomes an empty
|
|
// set the library refuses, not a partial one it might act on.
|
|
//
|
|
// Credentials pass through, and are never returned.
|
|
// lldap_set_password and lldap_create_user accept a password and hand it straight to
|
|
// the library. No action in either dispatch returns a stored credential, and nothing
|
|
// here writes one to a log.
|
|
//
|
|
// The destructive actions are POST-only by construction.
|
|
// Delete of a proxy, a user, or a group exists only in the POST match. The GET arm has
|
|
// five read actions and no others, so no link or prefetch can reach a delete.
|
|
//
|
|
// Authelia rule writes are atomic and refuse to create.
|
|
// The library writes .vv.tmp and renames, and returns 'Config not found' rather than
|
|
// authoring a fresh config — a config it created would carry no rules and a default
|
|
// policy, which is an accidental open door.
|
|
//
|
|
// The POST actions are CSRF-guarded by the platform, not by this file.
|
|
// Unraid's auto_prepend (webGui/local_prepend.php) validates a token on every POST and
|
|
// terminates the request before any code here runs. That guard is the reason every
|
|
// mutating action lives in the POST arm — this is the highest-value endpoint in the
|
|
// plugin to reach, since it can create a user and open a proxy host. The five GET
|
|
// actions are reads and are deliberately outside it. See README-unraid.md.
