iitm-network-auth

npm module to authenticate against the IIT Madras campus network using openLDAP credentials

Installation

npm install iitm-network-auth --save

Usage

Import the module

var IITMNetworkAuth = require('iitm-network-auth');

Create an instance

• Initialise with username, password and mode of login
  Modes that are availabe:
  • nfw: For the new firewall login (through https://nfw.iitm.ac.in)
  • TODO: netaccess: For the existing netaccess login (through https://netaccess.iitm.ac.in)

var auth = new IITMNetworkAuth('<username>', '<password>', '<mode>');

Login

auth.login();

Logout

auth.logout();

Keep the session alive

The module can keep an authentication session alive by sending request to keepalive url.
The current inteval is set to 9 minutes as the firewall keeps a session for 10 minutes.

auth.start_refresh();

Stop refreshing the session

auth.stop_refresh();

Refresh the session manually

auth.refresh()

Get login status

var logged_in = auth.is_logged_in();

Event listeners

The module emits events to denote certain actions as they happen. Any client code can subscribe to these events and take necessary actions

• Get the event emitter

var emitter = auth.get_emitter();

• Add event listeners

// do something when an error happens
emitter.on('error', function (e) {
    console.log(e.data); // log error details to the console
});

// do something when a login happens
emitter.on('log_in', function (e) {
    console.log(e.data); // log details to the console
});

// do something when a logout happens
emitter.on('log_out', function (e) {
    console.log(e.data); // log details to the console
});

// do something when a session is refreshed
emitter.on('session_refresh', function (e) {
    console.log(e.data); // log details to the console
});

// do something when a refresh timer is started/stopped
emitter.on('refresh_timer', function (e) {
    console.log(e.data.running); // log status to the consle (true/false)
});

Set new credentials

auth.set_credentials('<username>', '<password>');
