Hi All, We are having small issue with logging in to service(SSO Enabled) through tenant aware load balancer. I have setup tenant aware load balancer fronted 1 Identity Cluster and 2 appserver clusters. Problem is, i found that there is a looping problem between appserver and is clusters because logging requests doesnt have tenant domain in their URL's and then load balancer misunderstand it as a request to super admin(Tenant Id 0) and forward it to default cluster. One possible solution for this is setting tenant domain as a parameter to message context form identity side when user logging request comes and Tenant aware load balancer checks that parameter only if tenant id is 0.That is good solution in performance point of view.
What do you think?
