Content Hub enables syndication from content publishers to content subscribers. Publishers create content on their websites in their normal Drupal workflow, and Content Hub syndicates that content to subscribers along with any dependencies.
By default, the author of the content is included as a dependency. The author’s user entity is syndicated in full, complete with its roles and permissions, ensuring that the subscriber has all the information that it needs to build an exact replica of the content.
However, syndicating user entities may not always be desired. As of Content Hub 3.2.0, Content Hub allows finer control over the users and roles imported to subscriber sites.
Managing user syndication behavior
To manage user syndication on a subscriber:
- Go to Administration > Configuration > Acquia Content Hub.
Select the Import tab.
The system displays the Import control section with the following checkboxes:
- Disable user syndication
- Disable user role syndication
Disabling user syndication
By default, user entities are syndicated with content they have authored. Syndication of users can be disabled, preventing situations that would have otherwise imported them to a subscriber.
Select a proxy user (recommended)
When user syndication is disabled, the following are the options to manage content authors:
Select a proxy user that already exists on your subscriber account. The proxy user serves as the author of all imported entities on that subscriber. Acquia recommends creating a new user to serve as the proxy user.
Note
Existing, previously-imported content is not immediately re-authored when enabling a proxy user. Changes to content authors are only applied through the syndication process.
- When no proxy user is specified, Content Hub creates the user entity of the original author if it is missing on the subscriber. However, Content Hub does not syndicate additional updates to that user entity.

Note
User role syndication can be disabled with or without disabling user syndication.
