Connect error

Hi,

I created a database in debian using psql (as database user russell). My php4 script
can't access it. It reports:

   Warning: pg_connect(): Unable to connect to PostgreSQL server: FATAL:
       IDENT authentication failed for user "russell" . in /home/russell/public_html/hello.php on line 2

The script is:

   <?php
     $conn=pg_connect("dbname=parts_list user=russell");
     if(!$conn)
       exit(pg_result_error($conn));
   ?>

I have apache-1.3 running ok. In /etc/postgresql/pg_hba.conf, i
have "ident sameuser". I can access the database ok from my user
account using psql. What can i check now?
