LimeSurvey is a web survey software written in PHP.
LimeSurvey has a webserver authentication mode that allows one to integrate it directly into LemonLDAP::NG.
To have a stronger integration, we will configure LimeSurvey to autocreate unknown users and use HTTP headers to fill name and mail.
In Administration panel, go in Configuration > Parameters > Extensions manager. Select the WebServer module and configure it.
This is enough for the authentication part.
update lime_plugins SET active=0 where name="Authwebserver";
To configure account autocreation, you need to edit application/config/config.php: The configuration is done in config.php:
vi /var/www/html/limesurvey/application/config/config.php
'config'=>array( // debug: Set this to 1 if you are looking for errors. If you still get no errors after enabling this // then please check your error-logs - either in your hosting provider admin panel or in some /logs directory // on your webspace. // LimeSurvey developers: Set this to 2 to additionally display STRICT PHP error messages and get full access to standard templates 'debug'=>0, 'debugsql'=>0, // Set this to 1 to enanble sql logging, only active when debug = 2 // Update default LimeSurvey config here 'auth_webserver_autocreate_user' => true, 'auth_webserver_autocreate_profile' => Array('full_name' => $_SERVER['HTTP_AUTH_CN'],'email' => $_SERVER['HTTP_AUTH_MAIL'],'lang'=>'en'), 'auth_webserver_autocreate_permissions' => Array('surveys' => array('create'=>true,'read'=>false,'update'=>false,'delete'=>false)), )
