  Then why isn't it responding?  Are there firewall rules that filter
out the response or request?

  Then why did you configure the server to look the user up in LDAP?
It doesn't come configured to do that by default, so you must have
added that to your local config.

  Use 'tcpdump' to see where the packets are going.  See if you can
run 'radclient" on the same machine as the RADIUS server, and get a
response from the other server.
