Configuration parameters are added, updated, and retired with each release of the Centrify agent. In addition, some parameters are intended only for specific circumstances and are intentionally not documented in this guide. If a configuration parameter setting is recommended by Centrify Support, but not documented in this guide, you should consider the recommendation made by Support to be authoritative. You should also consider the comments in the configuration file to be the most authoritative reference for the release of the software you are using. Because parameters are often created to address specific issues in specific environments, the default values and recommendations for changes to the default values are also subject to change from one release to another.
