First, the auth=password is no longer used. Since 6.3, the network
protocol changed, and the client and server now negociate the
authentication scheme to use (based on pb_hba.conf).

Also, remember that postgresql users are not the same as unix users.
Unless you have used pg_password to create a password file, then use the
"ALTER USER" sql statement to set a password in the database.

Is the client holly aswell?

Do you have the pg_hba.conf file configured to allow the client's IP
address access? Even if they are the same machine, if you specify the host
name, rather name localhost, then you'll need to add the server's IP
address into the file aswell as 127.0.0.1
