You have a INTRANET environment where users/groups are synchronized across the Publish instances via Sling Distribution. Now you want to synchronize users/groups across INTERNET Publish instances as well, but you don’t want any INTRANET-users on INTERNET and vice versa.
What says Adobe in the documentation:
CONFIGURATION IMPROPERLY ADDED
When user sync fails to work, the most common problem is that additional configurations were added. Instead, the existing default configuration should have been edited.
With this sentence, you might think that it is not possible to add custom configurations… it is:
Follow the instructions under https://helpx.adobe.com/experience-manager/6-3/sites/administering/using/sync.html to configure the initial Sling Distribution for INTRANET. Then extend your configuration with the following information.
- The configured services typically matches on name property, so take care that all names are configured properly!
- The user usersync-admin needs to be created manually on INTRANET publishers and usersync-admininternet on INTERNET publishers. Also assign it to the administrators group and set ACL as it is documented at helpx.adobe.com.
