Если сделать ln -s /usr/share/mediawiki/extensions/LdapAuthentication/LdapAuthentication.php /usr/share/mediawiki/extensions/LdapAuthentication.php -- получаю в браузер "[89364da2c36790df5d1790ae] 2018-08-16 14:10:27: Fatal exception of type InvalidArgumentException", на чём пока любопытство и закончилось.
