pg_hba.conf and password files

Hi,

I use a pg_hba.conf like this:

local all trust
host all 127.0.0.1 255.255.255.255 trust
host all 134.93.64.0 255.255.255.0 password usr.txt

In usr.txt I made one entry "test:test". When I connect with Access, the DSN
dialog appears, and I enter "test" and "test" in the corresponding fields for
username and password. The connect fails, and the postgres.log says: "user
'wagner' not found in password file". It seems that the username "test" does
not make it to the backend, and my Windows username "wagner" is sent instead.

Any hints?

Thanks,

Markus
