ident authentication problem

Hi

I am running Mandrake 10 and would like to get sql-ledger to access the
database.

I can get in to the database with a local user at the command prompt and Web
Admin.

sql-ledger returns ident authentication problem.

the included faq
has this to say

  IDENT Authentication failed for user "postgres"

   This error has everything to do with the way distros set up access rights
for postgres. They are way too restrictive and leave you wondering what to do
next.

Do yourself a favour and change authentication type in pg_hba.conf to

local           all              trust

I can't locate this file.

Any suggestions as to how to get SQL-Ledger online?
