HowTo Upgrade Symas OpenLDAP


Important * Upgrades must be done as root or with root/administrator permissions * Always read the release notes for the version you are upgrading to. Upgrades sometime require a reload of the backend database. * An upgrade of versions will overwrite databases, schemas and .conf.default files. Make sure you have backups of all of these before proceeding.

Upgrading Symas OpenLDAP Packages for OpenLDAP 2.4 (and Above)

Instructions for the Symas built binary packages for OpenLDAP 2.5 (and up) can be found on the Symas OpenLDAP Package Repository

The simple explanation of the project is that the first time you install an OpenLDAP package from the Symas repository, you register the repository with your package manager. Then, you install the OpenLDAP software using the package manager, like any other package. Update/upgrade is then a matter of asking the package manager to install the new version of the OpenLDAP software.

The OpenLDAP Project and Symas recommend you let OpenLDAP be updated when the OS team installs updates for the rest of the platform. That way OpenLDAP fixes for function or security problems are installed in a timely way.
