We have agents all over the world (a sentence that sounds cooler than it actually is).
We also have Authentication Managers (one primary, several replica) all over the world.
I would like to make sure that agents prefer an AM server that is reasonably close to them, to reduce any slowness in the logon process.
How do agents choose which server they authenticate to? Do they ping the replicas first and work with the server that responds fastest? If not, is there a way to designate a "preferred" AM server for an agent?
