Trying to install a cardav plugin. using the composer phar install process.
Edited the config.inc.php and the composer.json to include the cardav plugin
firing up the composer phar installer I get the following error right off the bat.
php_uname() has been disabled for security reasons
I have looked into the /etc/php/7.0/apache2/php.ini file for any clues to this php_uname string, but, alas, no avail.
Any ideas would be a great help.
This is for a 16.04LTS Ubuntu LAMP stack running postfix/dovecot/roundcube 1.2.0/php7
