Script - Security change at low level
This is an administrator script that should be used only when it is necessary to propagate security changes under a folder that contains a significant number of nodes. These types of changes made from the UI can take a long time to propagate across the repository, and this script does it much faster.
Our recommendation is to use it when changes affect more than 100.000 nodes; otherwise, we recommend doing it from the UI.
The security change starts with a folder UUID node and propagates across all its children. The logic is to remove existing grants for each node and replace them with new ones based only on roles. Note that you can build other types of logic. Use the example as a basis.
- The variable UUID is the folder Unique Identifier.
- The variable MAX_DEPTH sets how deep the script should advance into subfolder children (note that 0 indicates the UUID folder).
- The arrays roleName and roleGrant are pairs of role names and role grants to be added.
- The variable LOG_FILE_NAME is the name of the log file saved in the $TOMCAT_HOME folder.
