pg_dump restore problem

Hi admin

i have problem with user authentification

I've made a dump from PostgreSQL 7.2.2 under linux 8.0 with the command:
pg_dump -a -b -Fc -f bakstore -o -v store

and running success, and then i try to restore with the command:
pg_restore -a -d store -Fc -o -v bakstrore

and running unsuccess because i've got message:
pg_restore:[archiver (db)] could not reconnect to database : FATAL 1 : IDENT
authentification failed for user "phpuser"

my post pg_hba.conf
*****************
TYPE DATABASE IP_ADDRESS MASK
AUTH_TYPE AUTH_ARGUMENT
host all 127.0.0.1
255.255.255.255 trust
host store 167.205.240.166 255.255.255.0
trust
host all 127.0.0.1
255.255.255.255 ident phpuser

my post pg_ident.conf
******************
MAP IDENT PGUSERNAME
phpuser phpuser postgres

NB: i make 'store' database pass through phpPgAdmin2.4.2 with
username:"phpuser" and password:""
