// Load the settings from the central config file

// Uncomment to enable debugging
phpCAS::setDebug();

// Initialize phpCAS

// For production use set the CA certificate that is the issuer of the cert 
// on the CAS server and uncomment the line below
// phpCAS::setCasServerCACert($cas_server_ca_cert_path);

// For quick testing you can disable SSL validation of the CAS server. 
// THIS SETTING IS NOT RECOMMENDED FOR PRODUCTION. 
// VALIDATING THE CAS SERVER IS CRUCIAL TO THE SECURITY OF THE CAS PROTOCOL! 
phpCAS::setNoCasServerValidation();

// set PGT storage to file in plain format in the same directory as session files
phpCAS::setPGTStorageFile('plain',session_save_path());

// force CAS authentication
phpCAS::forceAuthentication();

// at this step, the user has been authenticated by the CAS server
// and the user's login name can be read with phpCAS::getUser().

// moreover, a PGT was retrieved from the CAS server that will
// permit to gain accesses to new services.
