Installation

The phpCAS client can be obtained from Jasig at the following URL: https://wiki.jasig.org/display/casc/phpcas

Unzip the tarball to a location under your DocumentRoot for your PHP application.

tar xzvf CAS-x.x.x.tgz

For brevity, we will refer (going forward) to the location which the tarbell was unziped as PHPCAS_UNZIP_DIR

Configuration

To configure and use phpCAS, you must put the following block at the top of your code.

/* phpCAS CONFIGURATION */

//Import the phpCAS Library
include_once('./CAS.php');
 
// Initialize phpCAS
phpCAS::client(SAML_VERSION_1_1, "login.uconn.edu", 443, "cas");
phpCAS::setNoCasServerValidation();
//Perform Authentication
phpCAS::forceAuthentication();

Getting Authentication/Authorization Data

To get LDAP attributes asserted by CAS or to get the Authenticated user’s NetID, you will use the example code below after the phpCAS::forceAuthentication().

//Get Authenticated NetID
$netid = phpCAS::getUser();

//Get Data from the LDAP Assertion
$CASattribute = phpCAS::getAttributes();
$email = $CASattribute['mail'];
