To upgrade from OpenLDAP 2.2 to OpenLDAP 2.3 on CentOS 4.3, you need to update yum,
the automatic updater/package installer/remover for RPM systems. Then you’re ready to
upgrade your OpenLDAP packages. First, point yum at the CentOS development repository,
or repo, by adding these lines to /etc/yum.repos.d/CentOS-Base.repo:
[testing]
name=CentOS-$releasever - Testing
baseurl=http://dev.centos.org/centos/
$releasever/testing/$basearch/
enabled=1
gpgcheck=1
gpgkey=http://dev.centos.org/centos/
RPM-GPG-KEY-CentOS-testing
Next, upgrade your OpenLDAP packages using this command:
# yum -y install openldap.i386 openl
dap-clients.i386 openldap-devel.i386
openldap-servers.i386
Upgrading may take a while, as yum needs to update all packages related to OpenLDAP as well.
