- Configuration files and startup scripts from version 2.0 need minor adjustments particularly in module names which may have changed. Third party modules which worked in version 2.0 can also work in version 2.2 but need to be recompiled before you load them. Key modules that need to be noted are authentication and authorization modules. For each of the modules which has been renamed the
LoadModuleline will need to be updated.

Due to the vulnerability described in POODLE: SSLv3 vulnerability (CVE-2014-3566), Red Hat recommends disabling
SSLand using only
TLSv1.2. Backwards compatibility can be achieved using
TLSv1.0. Many products Red Hat supports have the ability to use
SSLv3protocols, or enable them by default. However, the use of
SSLv3is now strongly recommended against.
