This extension provides single sign on FROM MediaWiki TO Moodle. In addition it provides a signon facility in Moodle to authenticate against existing MediaWiki accounts (that have already been created by SSO).
Copy mediawiki-extensions-moodlesso to $IP/extensions/moodlesso
in LocalSettings.php add the following lines at the end
require_once( "$IP/extensions/moodlesso/moodlesso.php" );
$wgMoodlessoUrl = 'http://my.moodle.org/moodle';$wgMoodlessoUrl should be the url of your Moodle site (wwwroot).
Then go to maintenance/ directory and on the command line do,
php update.php
...to install the database table.
Copy the moodle-auth-mwsso plugin to auth/mwsso directory.
Visit 'Site administration > Notifications' to install.
Go to 'Site administration > Plugins > Authentication > Manage authentication' enable the MediaWiki plugin (by opening the 'eye') and then go to its Settings page. There is only one setting, it is the URL of the MediaWiki site.
In a MediaWiki page, simply add.
{{#moodle: moodle_path | Text}}
- moodle_path is optional, and is the path within moodle you would like to go to after login (e.g. /course/view.php?id=92). The Text is whatever you would like to appear on the page (e.g. 'Click to go to your Moodle courses')
When the page is rendered just the text appears as a link. Clicking it will take you to the Moodle site logged in. If you are not logged into MediaWiki you will, instead, be taken to the login page.
The MediaWiki users are created in Moodle with their own auth type 'mwsso'. No password is recorded in Moodle. If you log into Moodle with one of these users authentication will be attempted by Moodle calling a web service in the MediaWiki extension. If you convert them to manual users at any time you will need to supply a new password
SSO security is by a one time token which with a time-limited lifespan. Note that there is no encryption of data and the trust relationship is defined only by the hostnames specified at each end. This may not be sufficient security for a sensitive site. This is up to you to decide.
