Hello, I'm using the [clustering documentation](https://gluu.org/docs/ce/3.1.2/installation-guide/cluster/) to establish HA/Failover, and I've gotten all of my boxes to start successfully. However I'm using F5 load balancer as opposed to NGINX. I'm having problems maintaining my session across my nodes (i.e., logging in via the loadbalanced ip will fail if the authenticated box is not connected to), and had used Cluster Manager as an example for setup. My question is which part of the Cluster Manager setup is handling this authentication across the load balanced setup? I see that CM uses twemproxy, which is not in the manual clustering docs, is what does it? Thanks, Cory
