I am collecting,reading and trying to understand the concept of ldap. It really sucks me. New concepts and new difficulties but this is the attractive part of the job. According to my plan i want to start a mail server with ldap. I will use it in my home also in a private company for free. But at the working place it was already installed before i start to work here. So it will be very helpfull for me if i can. Also probably in May we will launch our new mail servers. It will serve 30000 clients in the future. I have to prepare for it. Difficulties are only a pleasure delayer for me. In apache 2 i have to add this lines in order to tell that this page must be compiled with php.
AddType application/x-httpd-php .php
AddType application/x-httpd-php .html
AddType application/x-httpd-php .php3
AddType application/x-httpd-php .htm
