The CAS Authentication plugin allows for StatusNet to handle authentication
through CAS (Central Authentication Service).
Installation
============
add "addPlugin('casAuthentication',
array('setting'=>'value', 'setting2'=>'value2', ...);"
to the bottom of your config.php
Settings
========
provider_name*: a unique name for this authentication provider.
authoritative (false): Set to true if CAS's responses are authoritative
(if authorative and CAS fails, no other password checking will be done).
autoregistration (false): Set to true if users should be automatically created
when they attempt to login.
email_changeable (true): Are users allowed to change their email address?
(true or false)
password_changeable*: must be set to false. This plugin does not support changing passwords.
server*: CAS server to authentication against
port (443): Port the CAS server listens on. Almost always 443
path (): Path on the server to CAS. Usually blank.
* required
default values are in (parenthesis)
Example
=======
addPlugin('casAuthentication', array(
'provider_name'=>'Example',
'authoritative'=>true,
'autoregistration'=>true,
'server'=>'sso-cas.univ-rennes1.fr',
'port'=>443,
'path'=>''
));
