I am requesting the ability to modify the LDAP authenticator to be able to specify multiple host names/urls.
If the first url is unreachable, the authenticator would failover to the next one, until it either finds one that is
reachable, or runs out of options.

I'm not talking about trying authentication of the user on each, just ensuring that if a particular host is unreachable,
we can try a backup host.

This is particularly important when a company gets in disaster recovery mode, so that the build server will
continue to function, even if the DC is pointed at a backup server until the primary is restored.
