Did You specified the database ? In PostgreSQL You are logging into
database, not into DBMS, like in MySQL.
For test users try template1 first, for example psql -h yourhost -U
somebody -d template1
Did You grant those users rights to database wchich they are connecting
to ?

You will need to modify pg_hba.conf file in the directory which you
initdb'ed and restart the database.

this file is well documented and reading it is a good investment.
There are several options to allow connecting . mentioned
below are roughly in order or security. you need to add/modity
/uncomment the lines near the end of this file.


local   all         all                               trust   # very trivial

will allow any user to connect from same machine to any database without
any password.

local   all         all                               md5

(same a above but will ask password)

host    all         all         192.168.0.100/32      md5

(same a above but allows connection from said address range)

you can choose any config based on your requirement but make
sure it secure enough eventually.
