The setup out of the server which hosts osticket is a Centos server running . apache with PHP 5.4 with LDAP extension. The MySQL database version is 5.5.25. I have checked the apache log and the only error in there was open.php has timed out. When the php.ini settings on script execution where extended from 30 to 60 seconds the script stopped timing out. Also, when the php script execution settings where at 30seconds the users would see Error 500, The sever has encountered an internal error. I've tried removing the LDAP mod from osticket and still no joy.
