BUG DESCRIPTION

I am using pgAdminIII, trying create a "New Server Registration". When I
connect to (localhost), it works fine. But when I change the host to the
actual workstation name, it says:

FATAL: no pg_hba.conf entry for host "fe80::c81c:9e9c:6570:d0bf%20", user
"postgres", database "postgres", SSL off

even when I have

host all all samehost md5

on pg_hba.conf on IPv4 and IPv6 settings.

PLEASE NOTE
I am trying to connect to the server from the same machine.

ADDITIONAL INFORMATION
If I connect to "SERVER" from other computers on the same network, it
works.

For further information, please contact.
