I'm working with a server running Debian 7.4 and it's currently running PHP 5.5.12 and Apache 2.2.22. I'm attempting to upgrade to Apache 2.4.9 so that I can enable Perfect Forward Secrecy.
I downloaded Apache 2.4.9 as source and successfully compiled it with these flags:
./configure --enable-so --with-included-apr --with-pcre --with-ldap --with-perl
I also downloaded PHP 5.5.12 as source and compiled with theses flags:
./configure --with-apxs2=/usr/local/apache2/bin/apxs --with-pdo-mysql=mysqlnd --with-openssl --with-gd --with-zlib --enable-shmop --enable-sockets --enable-sysvsem --enable-sysvshm --enable-mbstring --with-iconv --with-litespeed --with-ldap --with-mcrypt
I've done all of the necessary configurations (httpd.conf, etc) to Apache 2.4 to enable Perfect Forward Secrecy and enable all of the necessary modules (I think). I intentionally installed Apache 2.4 into a different directory from Apache 2.2 so that I can shutdown Apache 2.2 and start Apache 2.4 (it's a production server, can't afford downtime). Everything works great when I start Apache 2.4, except connecting to an LDAP server using PHP. No errors are thrown, it simply doesn't work; it's like it's timing out. The strange thing is that when I switch back to Apache 2.2, LDAP in PHP works just fine. Does anyone know why this may be happening?
