Node.js handler

Since version 2.0, a beta Node.js handler is available on GitHub and NPMJS.

Up-to-date documentation is available on GitHub.

Important things:

• Rules and headers must be written in javascript for these hosts (example $uid eq "dwho" becomes $uid === "dwho")
• Multi-lines are not supported in lemonldap-ng.ini
• Virtualhosts handled by node-lemonldap-ng-handler must be explicitly declared in your lemonldap-ng.ini file in [node-handler] section (NB: section [handler] isn't used by node handler):

[node-handler]
 
nodeVhosts = test.example.com, test2.example.com

server.js

var handler = require('lemonldap-ng-handler');
 
handler.init({
  configStorage: {
    "confFile": "/path/to/lemonldap-ng.ini"
  }
});
 
handler.nginxServer({
  "mode": "fcgi",   // or "http", default: fcgi
  "port": 9090,     // default value
  "ip": 'localhost' // default value
});

nginx.conf

server {
  #...
  # Internal authentication request
  location = /lmauth {
    internal;
    include /etc/nginx/fastcgi_params;
    fastcgi_pass localhost:9090;
 
    # Drop post datas
    fastcgi_pass_request_body  off;
    fastcgi_param CONTENT_LENGTH "";
 
    # Keep original hostname
    fastcgi_param HOST $http_host;
 
    # Keep original request (LLNG server will receive /lmauth)
    fastcgi_param X_ORIGINAL_URI  $request_uri;
  }
 
  # Client requests
  location / {
    auth_request /lmauth;
    auth_request_set $lmremote_user $upstream_http_lm_remote_user;
    auth_request_set $lmlocation $upstream_http_location;
    error_page 401 $lmlocation;
    include conf/nginx-lua-headers.conf;
  }
}

app.js

// Variables
var express = require('express');
var app = express();
var handler = require('lemonldap-ng-handler');
 
// initialize handler (optional args)
handler.init({
  configStorage: {
    "confFile":"test/lemonldap-ng.ini"
  }
});
 
// and load it
app.use(handler.run);
 
// Then simply use your express app
app.get('/', function(req, res) {
  return res.send('Hello ' + req.headers['Auth-User'] + ' !');
});
app.listen(3000, function() {
  return console.log('Example app listening on port 3000!');
});
