Mobile Friendly Authentication

Remote access to subscription databases is done through OCLC’s EZproxy Authentication and Access software.

EZproxy does not have built-in support for mobile devices.

How to make EZproxy Mobile Friendly

Incorporate a mobile device detection library?

EZproxy Ticket Authenticationhttp://ezproxy.yourlib.org:2048/login?

user=rdoe&ticket=a6911a5d0219f428b33e190a80818625%24c20041222220203&url=http://www.somedb.com/

“Ticket authentication allows remote systems to short-lived URLs that EZproxy will automatically recognize as being authorized to login and permit access to a resource with no need for EZproxy to check back with the program that creates the URL.” – OCLC website

Sample PHP code<?php

require("ezproxyticket.php"); $ezproxy = new EZproxyTicket("http://ezproxy.yourlib.org:2048", "shhhh", "someuser");

?>

<a href="<?php echo($ezproxy->url("http://www.somedb.com")) ?>">Some Database</a><br />

Central Authentication System (CAS)

Central Authentication Service (CAS) is a login service that allows you to access multiple password-protected web systems after logging in once on a central authentication server; this is often referred to as single sign-on.

http://www.jasig.org/cas

CAS vs IU CASStandard CAS response – XML

<cas:serviceResponse xmlns:cas='http://www.yale.edu/tp/cas'> <cas:authenticationSuccess> <cas:user>username</cas:user> <cas:proxyGrantingTicket>PGTIOU-84678-8a9d... </cas:proxyGrantingTicket> </cas:authenticationSuccess> </cas:serviceResponse>

IU CAS response –

If validation is successful, CAS sends back a two-line response with 'yes' on the first and 'username' on the second.

Connecting Ezproxy with IU CAS

1. Detect mobile or desktop

2. If mobile, set CASSVC to mobile

3. Check with CAS to see if already authenticated

4. If authenticated, display database; otherwise present a login screen

Sample Code – login.php<?php

include('mobile_device_detect.php');

if(mobile_device_detect(true,true,true,true,true,true,false,false)){

header("Location: https://cas.iu.edu/cas/login?cassvc=MOBIU&casurl=https://www.domain.edu/~site/cas/casauth.php");

}else{

header("Location: https://cas.iu.edu/cas/login?cassvc=IU&casurl=https://www.domain.edu/~site/cas/casauth.php");

}

?>

Sample Code – casauth.php<?php

session_start(); //start session

if( isset($_GET['casticket']) ){ //check to see if a ticket has been passed

$ticket = $_GET['casticket'];

} else {

$ticket = "";

}

Sample Code – casauth.php cont./*

* check CAS ticket authenticity and get the user's uid back

* the variable $contents will have the string

* "ticket '<ticket value>' not recognized" if a bad ticket

* has been provided.

*/

$casXML = fopen("https://cas.iu.edu/cas/validate?cassvc=IU&casticket=$ticket&service=https://www.domain.edu/~site/cas/casauth.php","r");

$contents = fread($casXML, 1024);

fclose($casXML);

Sample Code – casauth.php cont.list($yesno, $netid) = split("\n", $contents, 2);

$authok = trim($yesno);

$iuid = trim($netid);

if ($authok == "no") {

header("Location: https://www.domain.edu/~site/cas/login.php");

}

else {

$_SESSION['auth'] = $iuid;

header("Location: https://www.domain.edu/~site/cas/success.php");

}

?>

A Better Idea – Can IU Mobile do it?

IU Mobile is already connected to IU CAS

Need ability to • Check if authenticated• Display alternative information if not• Restrict to campus level

Yes, IU Mobile Can do it!<authenticated>

Authenticated vs. Not-Authenticated

Sample restriction to South Bend<list-item>

<authenticated>

<if permission="southbend">

<link type="external" url="<?php echo($ezproxy->url("http://vnweb.hwwilsonweb.com/mobile/jumpstart.jhtml")) ?>" title="HW Wilson" />

Computer Availability Mobile Webpage

http://m.iusb.edu

System Requirements

Computer Availability

• Web Server such as Apache or IIS• PHP• Database such as MySQL• Ability to run login and logout scripts

How it works

• Script run at login updates database

• Script run at logout updates database

• Standard html version available at www.iusb.edu/~labseats

For mobile, output data as XML<seats> <?php

foreach ($regions as $region) { $region_id = $region['region_id'];

$region_display_name = $region['display_name'];

$region_location = $region['location'];

$region_mac_status_counts = get_status_counts_for_region($region_id, 'Mac');

$region_pc_status_counts = get_status_counts_for_region($region_id, 'PC');

$total_idle_mac_computers = $region_mac_status_counts['idle'];

$total_busy_mac_computers = $region_mac_status_counts['busy'];

$total_idle_pc_computers = $region_pc_status_counts['idle'];

$total_busy_pc_computers = $region_pc_status_counts['busy'];

$total_idle_computers = $total_idle_mac_computers + $total_idle_pc_computers;

$total_online_computers = $total_idle_computers + $total_busy_computers;

print "<seat lab=\"$region_building $region_location\" building=\"$region_display_name\" availability=\"$total_idle_computers/$total_online_computers\" campus=\"

SB\" /> \n”; }

?> </seats>

Planning for Mobile Website

1. Needs assessments

2. Integrate with existing library services

3. Project planning

4. Build the site

5. Testing, marketing, launching

6. Keeping up
