11. 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.

12. How to make EZproxy Mobile Friendly Incorporate a mobile device detection library? http://detectmobilebrowsers.mobi/

13. EZproxy Ticket Authentication http://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

14. 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 /> EZproxy user.txt ::Ticket TimeValid 90 MD5 shhhh Expired; Deny expired.htm /Ticket

15. 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

16. 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.

17. Connecting Ezproxy with IU CAS • Detect mobile or desktop • If mobile, set CASSVC to mobile • Check with CAS to see if already authenticated • If authenticated, display database; otherwise present a login screen

18. 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"); } ?>

19. 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 = ""; }

20. 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);

21. 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"); } ?>

22. 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

23. Yes, IU Mobile Can do it! <authenticated> <list-item> <link type="xml" xml="http://it.iusb.edu/demo2.php" title="Subscription Databases" /> </list-item> </authenticated> <not-authenticated> <list-item> <link type="xml" xml="http://library.iusb.edu/miuxml/oopsSubscribed.xml" title="Subscription Databases" /> </list-item> </not-authenticated>

24. Authenticated vs. Not-Authenticated

25. 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" /> </if> </authenticated> </list-item>

26. Computer Availability Mobile Webpage http://m.iusb.edu

27. System Requirements Computer Availability • Web Server such as Apache or IIS • PHP • Database such as MySQL • Ability to run login and logout scripts

28. How it works • Script run at login updates database • Script run at logout updates database • Standard html version available at www.iusb.edu/~labseats

29. 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>
