FATAL: password authentication when bucardo add tables

System specification:

• Ubuntu 14.04
• bucardo version 4.99.10
• psql (PostgreSQL) 9.3.14

What I have tried so far?

I have created master database with openerp postgres user.

- Setup Source Database

    export SOURCE_HOST=localhost
    export SOURCE_PORT=5432  
    export SOURCE_DATABASE=master
    export SOURCE_USERNAME=openerp  
    export SOURCE_PASSWORD=openerp

- Setup Destination Database

    export DEST_HOST=localhost 
    export DEST_PORT=5432  
    export DEST_DATABASE=slave  
    export DEST_USERNAME=openerp  
    export DEST_PASSWORD=openerp    

- Finally, the tables to be migrated

    export TABLES="-t res_partner"

    export TABLES_WITH_SPACES="res_partner"

- Set up the Destination Database

    cat >> $HOME/.pgpass <<EOL  
    $DEST_HOST:$DEST_PORT:$DEST_DATABASE:$DEST_USERNAME:$DEST_PASSWORD
    $SOURCE_HOST:$SOURCE_PORT:$SOURCE_DATABASE:$SOURCE_USERNAME:$SOURCE_PASSWORD
    EOL  

- Create schema.sql 

- Create Slave database

- Load schema into Slave

- Setting up Bucardo Sync (Source Database and  Destination Database) 

- Now I am trying to add the tables we want to migrate and add them to a "copying herd"

    ./bucardo add tables res_partner db=master

I got following error:

openerp@odedra-Lenovo-Z50-70:/usr/local/src/bucardo$ ./bucardo add tables res_partner db=master DBI connect('dbname=master;host=localhost;port=5432','openerp',...) failed: FATAL: password authentication failed for user "openerp" FATAL: password authentication failed for user "openerp" at ./bucardo line 8632.

I have analytic script bucardo. I have confusion with dbuser and dbpass variable declared at line number 84, 85.

(I have tried with dbuser = 'openerp' and dbpass='openerp' but result same)

My pg_hba.conf

May you guide me what should I change to fix above error or helpful related links?

How can I achieve master-slave functionality using Bucardo ?
