Authorizer limits login attempts, restricts access to specified users, and authenticates against external sources (e.g., Google, LDAP, or CAS).

== Description ==

*Authorizer* restricts access to a WordPress site to specific users, typically students enrolled in a university course. It maintains a list of approved users that you can edit to determine who has access. It also replaces the default WordPress login/authorization system with one relying on an external server, such as Google, CAS, or LDAP. Finally, *Authorizer* lets you limit invalid login attempts to prevent bots from compromising your users' accounts.

*Authorizer* requires the following:

* **CAS server** or **LDAP server** (plugin needs the URL)
* PHP extentions: php5-mcrypt, php5-ldap, php5-curl

*Authorizer* provides the following options:

* **Authentication**: WordPress accounts; Google accounts; CAS accounts; LDAP accounts
* **Login Access**: All authenticated users (all local and all external can log in); Only specific users (all local and approved external users can log in)
* **View Access**: Everyone (open access); Only logged in users
* **Limit Login Attempts**: Progressively increase the amount of time required between invalid login attempts.

== Installation ==

1. Upload the `authorizer` directory to the `/wp-content/plugins/` directory
1. Activate the plugin through the 'Plugins' menu in WordPress
1. Specify your server details in the 'Settings' menu in WordPress
