[9fans] Multiple auth servers

[9fans] Multiple auth servers

[Akshat Kumar]

I recently added an auth server to my network.
For internal connections, my terminals connect
directly to that auth server with the local domain
(authdom=hetero). However, for incoming
connections from remote clients (outside the local
network), instead of using trampoline(1) to forward
requests on authsrv from the cpu server to just one
auth server, I'd like it if there was some way that
the cpu server could decide which auth server in the
local network to use (suppose there are multiple
auth servers), based on the given authdom.
So, if the client-side configuration looks like:

auth=server authdom=auth1

then the CPU server maps "auth1" (perhaps by
a /lib/ndb/local entry that looks like:

auth=intauth authdom=auth1

where intauth is one of the auth servers, at say,
192.168.1.4). That way, I don't need a new public
IP for each auth server; I don't need a new port for
each auth server; I can keep my auth servers away
from direct access; etc....

Has anything like this ever been implemented? Are
there any existing solutions or near-solutions for such
a problem?


Thanks,
