Mobile friendly authentication l.jpg




Mobile Friendly Authentication

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

Mobile Friendly Authentication

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

How to make EZproxy Mobile Friendly

Incorporate a mobile device detection library?

Ezproxy ticket authentication l.jpg
EZproxy Ticket Authentication

“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 l.jpg
Sample PHP code

<?php require("ezproxyticket.php"); $ezproxy = new EZproxyTicket("", "shhhh", "someuser");


<a href="<?php echo($ezproxy->url("")) ?>">Some Database</a><br />

EZproxy user.txt


TimeValid 90

MD5 shhhh

Expired; Deny expired.htm

Central authentication system cas l.jpg
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.

Cas vs iu cas l.jpg

Standard CAS response – XML

<cas:serviceResponse xmlns: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 l.jpg
Connecting Ezproxy with IU CAS

  • Detect mobile or desktop


  • Set CASSVC (service)

    • If detect mobile, set service to mobile

  • Check with CAS to see if already authenticated

  • If authenticated, display database; otherwise present a login screen

Sample code login php l.jpg
Sample Code – login.php









Sample code casauth php l.jpg
Sample Code – casauth.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 l.jpg
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.


$casXML = fopen("$ticket&service=","r");

$contents = fread($casXML, 1024);


Sample code casauth php cont26 l.jpg
Sample Code – casauth.php cont.

list($yesno, $netid) = split("\n", $contents, 2);

$authok = trim($yesno);

$iuid = trim($netid);

if ($authok == "no") {



else {

$_SESSION['auth'] = $iuid;




A better idea can iu mobile do it l.jpg
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 l.jpg
Yes, IU Mobile Can do it!
