Linux user www-data has no access to amphora2 DB

Hi pgsql-admin,

i want to install the amphora2 light groupware software under Debian Woody
with pgsql 7.2.1. I have to restore a dump into the amphora2 DB that
i created before.:
-----------------
testlinux:/home/amphora2/inst# su www-data -s /bin/bash -c 'psql amphora2 < amphora2.0.dump'
-----------------

but postgres tells me:

-----------------
psql: FATAL 1: IDENT authentication failed for user "www-data"
-----------------

my pg_hba.conf:

local amphora2 ident amphora
local all ident sameuser
host all 127.0.0.1 255.0.0.0 ident sameuser
host all 0.0.0.0 0.0.0.0 reject
