Sling Content Distribution is a feature that allows synchronizing user data across publish servers in a
publish farm. Sling Content Distribution uses agents to distribute content from one instance to
another using a publish-publish topology. Sling Content Distribution can be configured to synchronize
user data under /home/users and /home/groups paths, as well as their ACLs. Reference:
