Any time you add a new user on your cluster’s head node or make changes to an existing user, you will need to synchronize those changes across the entire cluster. Advanced Clustering makes this a simple task by using our act_authsync utility. This utility takes all system user configuration files and pushes them out to the nodes that you specify. An example of pushing users’ changes out to every node in your cluster is:

$ act_authsync -a
CODE

If you want to push changes only to a specific group of nodes you can use the syntax:

$ act_authsync -g <group list name>
CODE

For a list of all act_authsync options:

$ act_authsync -h
