Multiple auth servers in config doesn't work if the last on is not reachable.

[nmaki]

I have multiple auth servers listed in my config file. Not all the auth servers are necessarily up so I would expect the service to loop through all the listed auth servers until it can connect to one. I'm only seeing it attempt to connect to the last one though. Lets say I have the following config.
auth_servers: - 10.1.0.2:3025 - 10.1.0.3:3025 - 10.1.0.4:3025 - 10.1.0.5:3025 - 10.1.0.6:3025
Assume 10.1.0.6 is not reachable at the time an ssh server is coming up. An ssh server will loop forever only trying to connect to the last server in the provided list.

@nmaki Can you show what's in the authservers.json file in /var/lib/teleport?

[nmaki]

@klizhentas there is no authservers.json in the folder /var/lib/teleport. The node has not joined a cluster yet.

It looks like this line might be the culprit?

teleport/lib/config/configuration.go

Line 138 in 5a0e061

cfg.AuthServers = []utils.NetAddr{*addr}
