Thread:Project:Support desk/Regarding Shibboleth Authentication Plus Plugin

Hello, I have installed latest version of mediawiki 1.16 on CentOS and want to use single sign on (SSO) functionality provided by Shibboleth Authentication Plus plugin but there are few problems with environment variables. The ShibAuthPlusPlugin.php uses few of the server variables like $_SERVER['HTTP_SHIB_EP_ORGUNITDN'] which seems not to be set by the server running on this machine.This variable is used for group based authentication. From one of the sources, I have read that lazy sessions needs to turned on in shibboleth.xml for supporting Shibboleth Authentication Plus Plugin. Can anybody please confirm on same, as it is an secured environment and avoid making changes that I am not sure about As per my knowledge we cannot explicitly set server variables nor there is any provision in LocalSettings.php for a developers to do so. I have retrieved the SERVER variables but could find the above mentioned variable being set. Please let me know if there is any link I can refer.Thank you.
