Syncronization does not work on standalone cluster in RH-SSO 7.2 deployed in Docker with overlay networks configured

Issue

Synchronization are not work on a Red Hat Single Sign-On 7.2 based on Docker 1.2 with overlay networks configured ¹ like:

• The Access Token obtained on the one node of the cluster is not valid for other nodes;
• The client created in the one node of the custer do not appear in the other nodes;
• The changes in the clients are not replicated on other node until we clear the caches.
