can not connect to pg on linux FC4

Hi,
I use pg 8.03 (come with FC4). I can not connect to pg
because of Ident authentication failed for user "root"
error. pg_hba.conf
host all all 127.0.0.1/32 ident sameuser

Then I try another way by add adding a row to pg_indet
so that I can use root account to connection to db.
mymap root root
and chage "sameuser" to "mymap" in the pg_hba.conf.
But I can not connect too as the above error.

Thank in advande someone help me.

Onother question. Is there a way that I can create a
user using password authetication at the situation I
have no pg account like this sitation?.

Thanks.

Fucai
