Installing php-ldap on CentOs

Question

I have an unmanaged VPS server preinstalled with CentOs 6.6 and WHM/CPanel. I am trying to install php-ldap but it just says package not found. I have not been able to find anywhere what repository it should be in. How can I install ldap on my server to work with php 5.4? I am trying to manage Windows Server 2012 R2 Active Directory.

root@vps [~]# yum install php-ldap
Loaded plugins: fastestmirror, security

No package php-ldap available.
Error: Nothing to do
root@vps [~]#

Answer 1

On a cpanel serveur you probably have an "exclude" line in yum.conf (see I can't install any package related to PHP with yum) which prevent you to install/upgrade php from another repository.

To see the provider of "php", user this command

rpm -qf $(which php) 

And the ldap extension, if available will be in the same namespace.

Notice switch the php stack from the cpanel provider to another repo can break it.
