## Description

This plugin reserves a collection of URIs that create, validate, and destroy CAS
tickets.

 * /cas/login :: If user is not authenticated he/she is redirected to the login 
   page. Otherwise the user is redirected to the service specified as a GET variable
   in the URL – or if service is not provided, the user is redirected to the WordPress
   instance’s home.
 * /cas/logout :: The user’s session is destroyed, user is logged out of the WordPress
   instance, and redirected to $_GET[‘service’] (or the blog home if service isn’t
   provided)
 * /cas/proxyValidate and /cas/validate :: The CAS ticket must be passed as a GET
   parameter in the URL when calling /cas/validate. The ticket is validated and 
   XML is output with either cas:authenticationSuccess or cas:authenticationFailure

### Hooks & Filters

#### wpcas_server_login Hook

This hook allows for the insertion of code after login has successfully completed
and just before the ticket creation. One common use of this hook is to fill out 
the $_SESSION variable with site/user specific information.

#### wpcas_server_auth_value Filter

This filter (executed in a successful ticket validation in /cas/validate) is used
to override the user identifier returned in the cas:authenticationSuccess XML response.
By default, the value returned is the $user_ID of the authenticated user. Using 
this filter, that value can be altered to whatever suits your implementation.

## Installation

 1. Upload `wpcas-server` directory to the `/wp-content/plugins/` directory
 2. Activate the plugin through the ‘Plugins’ menu in WordPress

## FAQ

  What version of CAS does this plugin replicate?

wpCAS Server currently replicates partial functionality of a CAS 2.0 server.

  You just said “partial”…what doesn’t this support?

Currently wpCAS Server has not implemented the Proxy ticketing found in the [CAS 2.0 architecture](http://www.jasig.org/cas/cas2-architecture).
