phpCAS and WordPress

Make sure your account is in the “Administrator” role, as you won’t be able to login as admin after switching to CAS.

1. Download phpCAS and unzip/untar it:

2. Download and unzip it in wp-content/plugins

3. edit wp-content/plugins/wpcas/wpcas.php and remove or comment out line 57:

/* $wpcas_options['server_path'] == '' || */

4. Create wp-content/plugins/wpcas/wpcas-conf.php with the following content (change “/path/to” to the path to CAS.php that you installed in step 1):


// the configuration array

$wpcas_options = array(

'cas_version' => 'S1',

'include_path' => '/path/to/CAS.php',

'server_hostname' => '',

'server_port' => '443',

'server_path' => ''


// this function gets executed

// if the CAS username doesn't match a username in WordPress

function wpcas_nowpuser( $user_name ){

die('you do not have permission here');



4. Login with an account that’s in the Administrator role.  In “Plugins”, activate the wpCAS plugin.

5. If possible, test in a separate browser.  When you click “Log in” you should be redirected to  Type in your PatriotPass NetID and password.  You should be redirected back to your WordPress site.
