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 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
<?php
require("ezproxyticket.php");
$ezproxy = new
EZproxyTicket("http://ezprox
y.yourlib.org:2048", "shhhh",
"someuser");
?>
<a href="<?php
echo($ezproxy>url("http://www.somedb.co
m")) ?>">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 CAS
Standard 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.e
du/~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&servic
e=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 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")) ?>"

Web Server such as Apache or IIS
PHP

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\"
