I use Fedora 18 operating system in my computer and username openerp exists..

I downloaded postgresql 9.2 from www.postgres.org, and installed with database user name openerp and password.

I installed openerp-server and openerp-client  6.1  which is in Fedora 18 package.

Now successfully both postgresql and openerp-server are running.

Then I launched openerp-client with "local all all  password" in pg_hba.conf file.

However, in openerp-client window shows database: "couldnot connect to server".

Next I changed "local all all    trust" in pg_hba.conf file, and again rebooted.

This time when I launched openerp-client again, the openerp-client window displays "Authentication errors: Bad Username or Password"

In conclusion I failed to launch openerp application.

I would like to know  what's the problem!
