[keycloak-user] Keycloak Clustering Issues

[Marek Posolda]

That's quite strange. I've just tested same scenario and works fine for 
me. If you do any change on user, the user is invalidated from cache on 
node-1 and this change about invalidation should be propagated to node-2 
. As long as you have shared database, node-2 should then retrieve 
newest data about shared user from database.

I would suggest to try this:

* Make sure that your infinispan cluster is correctly set. You can check 
it by seeing the message similar to this in server.log of both nodes: 
node_1 | 10:49:50,344 INFO 
[org.infinispan.remoting.transport.jgroups.JGroupsTransport] 
(Incoming-10,shared=udp) ISPN000094: Received new cluster view: 
[node1/keycloak|1] (2) [node1/keycloak, node2/keycloak]

* Make sure that you enable "infinispan" as provider of realmCache and 
userCache and configured connectionsInfinispan . When you open admin 
console on any node like: 
http://node-1:8080/auth/admin/master/console/index.html#/server-info

you should see:
connectionsInfinispan default
realmCache infinispan
userCache infinispan
userSessions infinispan

* If still seeing issues, you can try to enable trace logging for 
"org.keycloak.models.cache.infinispan" category.

Hope this helps,
Marek
