We're having a bit of an issue with our local Windows AD not failing over to our AWS hosted AD.
We have web portals for our support staff to log into with AD credentials. When our on-premise AD "fails" we are unable to authenticate with our AWS Windows AD controller.
Our Controllers replicate file storage and users, but I don't know where to look to troubleshoot authentication issues. I inherited this setup and unfortunately do not have contact with the admin that setup it up.
Could anyone point me to some doco about failover or logging or anything that may be helpful?
