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• http://detectmobilebrowsers.mobi/

2. Set CASSVC (service)• If detect mobile, set service 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>

<if permission="southbend">
