The GConf adapter is part of the apoc-adapter-gconf package. When you install the adapter from the corresponding RPM, the GConf data sources path in /etc/gconf/2/path is updated to include the Configuration Manager sources. A backup of the old path is stored in /etc/gconf/2/path.apocBackup. If the old path refers to custom data sources, you will need to update the path by merging the changes from the default path to the newly installed Manager path. The two data sources that are provided by the adapter are:
"apoc:readonly:": provides access to non-protected settings from the policies. Insert this data source after the user settings and before the local defaults.
"apoc:readonly:mandatory@": provides access to protected settings from the policies. Insert this data source after the local mandatory settings and before the user settings.
