vCenter SSO HA

Hi,

anyone using the vCenter SSO in HA ?, I followed the SSO deployment guide for vRA but the automatic failover does not work, if I shutdown on of the nodes we start to get exception errors creating tenants,adding bussiness group,... with both nodes works fine ( load balancer seems ok )

Any experience with vCenter SSO 5.5up2 HA and vRA 6.2.2 ? is there anything missing in the guide or any extra settings to configure  ?

Thank you.
