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

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:""
